    Description

    The HI83749 Portable Turbidity and Bentonite Check Meter ensures protein stability before bottling for great quality wine. The HI83749 measures turbidity of samples from 0.00 to 1200 NTU (Nephelometric Turbidity Units) and is USEPA compliant.
    • Log and transfer up to 200 measurements.
    • GLP (Good Laboratory Practice) feature for traceability of the calibration conditions.
    • Great for small & medium wineries and advanced hobbyists.
    The HI83749 Portable Turbidity and Bentocheck Meter is specially designed for measurement of turbidity in wine. The instrument is based on a state-of-the-art optical system which guarantees accurate results, assures long term stability, and minimizes stray light and color interferences.

The 25 mm round cuvettes composed of special optical glass guarantee the repeatability of turbidity measurements.
     
    Features at-a-glance
     
    AMCO AEPA-1 Primary Turbidity Standard - The AMCO AEPA-1 supplied standards are recognized as a primary standard by the USEPA. These non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density. The standards are reusable and stable with a long shelf life.
     
    Calibration – A two, three, or four-point turbidity calibration can be performed by using the supplied (<0.1, 10, 100, and 500 NTU) standards. Calibration points can be modified if user-prepared standards are used.
     
    Fast Tracker™ - For users taking measurements throughout the winemaking process, the HI83749 is equipped with Fast Tracker™ - Tag Identi˜fication System (T.I.S.) that makes data collecting and management simpler than ever. Fast Tracker™ allows winemakers to record the time and location of a speci˜fic measurement or series of measurements using iButton™ tags on specific tanks for quick and easy readings. Each iButton® tag contains a computer chip with a unique identi˜cation code encased in stainless steel.
     
    GLP Data – The HI83749 features complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. Data includes calibration points, date, and time.
     
    Data Logging – Up to 200 measurements can be stored in the internal memory and recalled at any time.

    Significance of Use
    Unrefined wine is quite turbid and hazy from suspended solids produced during fermentation. The unrefined wine is treated with fining agents to reduce cloudiness. This cloudiness is what winemakers refer to as protein haze, or haze for short. Thaumatin-like proteins (TLPs) and chitinases are the primary grape proteins responsible for haze formation. These positively charged proteins degenerate and stick together, resulting in undesirable flocculent clouds and visible haziness.
     
    The prevention of protein haze or deposit in bottled white wines is a universal concern and often a wine needs to be stabilized before bottling. One commonly used stabilization agent is bentonite. Bentonite is a volcanic clay earth type fining agent (like kaolin) that acts as a wine stabilizer. It improves the clarity of wine but has also negative aspects because of the volume of lees formed, reduction of tannin and color. Since there are different types and qualities of bentonite with different capacity of protein removal, it is important to make laboratory trials with the same lot and wetting degree of the bentonite as that will be used in the cellar.
     
    Protein stabilization is normally not a problem in bottled red wines because of the relatively high concentration of phenols that binds and precipitates with the unstable proteins before bottling. Often bentonite is added to red wines at a level of about 12 g/hL (1 lb/1000 gal), reducing colloidal suspended particles thus improving membrane filterability.
     
    Wines with low phenols contents, such as rose, light reds and whites should be checked for protein stability before bottling. Hanna offers a rapid test to verify the risk of future protein haze formation. If protein instability is detected, a next test can help defining the right amount of bentonite to be added for improving protein stability. It is important not to overdose bentonite, avoiding stripping wine flavour, body, and significant loss of color, especially in young red wines. Moreover, adding only the necessary amount of bentonite to obtain the desired protein stability results in a reduction of costs.
     
    Winemakers can determine the initial turbidity of the unrefined wine with the HI83749 turbidity measurement instrument. After taking a turbidity reading the pre-made HI83749-20 Bentocheck Solution is added to the wine sample. A second turbidity measurement is taken. If the second turbidity reading is less than the initial turbidity reading plus 2 NTU, the wine can be considered stable. Otherwise a fining trial can be performed to determine the amount of bentonite that must be added to stabilize the wine.
    Principal of Operation
    To measure turbidity the HI83749 passes a light beam through the sample that is scattered in all directions. The intensity and pattern of the scattered light is affected by many variables, such as wavelength of the incident light, particle size and shape, refractive index, and color. The optical system of the HI83749 includes a tungsten fi˜lament lamp, a scattered light detector (90°) and a transmitted light detector (180°).
     
    The HI83749 features a powerful microprocessor that calculates the NTU value from the signals that reach the two detectors. An effective algorithm is used to correct and compensate for any color interferences. The optical system and measuring technique also compensate for fluctuations in lamp intensity, minimizing the need for frequent calibration.
    The HI83749-11 AMCO AEPA-1 standards ensure that measurements are traceable to primary reference materials. These standards are used for calibration and performance verification of the turbidity meter.

        I got my kit from CellarScience as they always have great products. First off the test works great. But I do have some issues. They give you enough acid standard to run hundreds of test. They are very generous with paper and capillary tubes. My lower rating is due to the jar and the developer. The 4 oz bottle of developer will not nearly do the 25 pages of test. The jar has a ridge in the bottom. When you set the paper in it makes it tilt over and it also raises the paper on an angle which makes it barely touch the liquid. I would have thought that the kit would contain enough developer to use up the stack of paper. The pix shows an 8 oz bottle of developer. Perhaps a mistake?

        My 1st Refractometer

        This is a neat device. Some things that may assist you are: 1.) first test it with distilled water and adjust accordingly via the circular piece on the bottom. You can use a flat head or your finger. Note the entire plastic movable flap must be covered in liquid to produce an accurate reading. 2.) refractometers should be used to measure the sugars in the mash and after the boil. Note this device measures accurately at 20 Celsius (68 Fahrenheit) so if you take a reading below or higher than 20 Celsius then search for a refractometer correction chart in Google to aid in adjusting for the temperature difference. 3.) this refractometer is not designed to read final gravity due to alcohol being more dense which makes the final gravity appear lower. I've heard of some that do read alcohol but some people say they are not accurate (off by 10% abv or so). The cheapest and sure way is to have a hydrometer and a hydrometer jar to measure the final gravity. Use the refractometer for everything else because it's faster and waste less wort. 4.) this refractometer is designed to be used with natural light so the better the light the clearer the lines of your reading.

        absolutely needed for Brewzilla Gen4 but.....

        absolutely needed for Brewzilla Gen4 because without it you're literally flying blind as to what the temperature of the actual mash is. The integrated temp probe at the bottom of the brewery can reach and overshoot target temps much faster than the mash temp. The problem is that it is cheaply made like much of Kegland's electronic devices and incredibly there is no way to calibrate it. First one I bought (from another vendor) went way out of calibration just before the warranty. The one I bought here died after just a month and two uses.

        Wonderful to use but there are Hidden Charges

        I've been very impressed with my unit and couldn't go back to my old methods of measuring SG. I am however very annoyed at the hidden charges for storing information within the app. After 10 batches a fee of $39.99 is now required that is scandalous. Nowhere was this information visible when I purchased my init from MoreBeer. I guess Anton Par assumes that once you've brewed 10 bathes you now qualify as "Pro". This is an expensive quality instrument please don't cheat us once we've purchased it.

        Works just like it did 10 yrs ago when I bought it

        I've had this going on 10 years now. Works reliably and as intended. The materials used have not shown any sign of degradation and still work as good as it did through hundreds of brews. I use this as my after boil chill loop to make sure wort is good temp before sending it to the fermenter. - magicalpancake

        Seems to work ok.

        The unit had to be calibrated right out of the box. No big deal I had bought ph calibrating solution. I tried the 7.0 solution and the meter read 6.8. I adjusted it like the directions said. I then tried it in test solution that was 4.0 and it was spot on. The reason for the 3 stars is when I opened the battery compartment to pull out the insulating strip the battery in the center was exploded. I took them out and a metal clip fell out too. I got that put back in and got some fresh batteries. It takes 3 batteries and there is no way they fit. All 3 fit in the compartment but there was so much space they could not begin to make contact. I had to jam a wad of aluminum foil into the space at the end of the row of batteries. The meter seems to work ok. But gee I really didn't think economy meant poor quality. It works but I really do not recommend this product.

        This is the best thing on the market

        Very easy to use all you need to get precise information on OG final gravity ABV of the final product. When I got my hands on this equipment my life became much easier and happier! P.S. very quick replies from customers service Highly recommend for brewers

        While pricey it's worth it.

        I watched all of the videos and the speed and accuracy of this device is mind blowing. The smartref opens a lot of doors from beer to meed to fruited beer to checking your glycol concentration on your glycol chiller or more... they have multiple apps depending on the use and still curious to try some of the other features. It takes about two seconds to give you a number and a temp. Heartily recommend this bad boy

        Can't answer my own questions on MB so....

        I wrote a series of questions to Anton Paar after submitting them to MoreBeer. It won't let me post a response to my own question so I hope this helps....: ------- 1)Just to be clear: You're saying I can obtain an accurate (within half a percent) ABV reading without any kind of Original Gravity record? Yes the combination of EasyDens with SmartRef allow the measurement of density and refractive index. By knowing these two measurement values it is possible to calculate the ABV with an accuracy of 0.5 % v/v. 2) If I'm measuring fruited / adjunct beers is the ABV% reading still reliable and in the same 0.5% margin of error? Unfortunately it does not work if you add fruits. In this case there is additional sugar which influences the measurement and the result will be incorrect. 3) On the 'SmartRef' individual item page on MoreBeer they have this statement "EasyDens gives accurate readings at any point during fermentation without the need for an original reading." Does this mean I can pull ABV without an OG measurement with just EasyDens (rather than as part of the EasyDens-SmartRef combo) No this is not correct. You cannot measure ABV of beer using only EasyDens. If you are just using EasyDens for alcohol calculation you will need OG and FG. But EasyDens does the calculation of the estimated alcohol content fully automatically. 4) On the EasyDens individual page MoreBeer has this statement: Features Free: Basic features and all measurement units Premium features: Free for one year". Given that Is ABV-without-OG considered a measurement unit or a premium feature? You can perform 10 ABV measurements per month for free if you need more ABV measurements per month you will need the premium version. 4.a) Eitherway what are the costs of the premium features of the apps and what are those premium features? Information about in-app purchases can be found in your Apple App Store or Google Play Store. There are several premium features like Temperature coefficient free selectable Higher resolution for most measurement values Unlimited batches in the app Unlimited ABV measurements two different units free selectable on the display I hope this information is helpful to you. If you have any further requests do not hesitate to contact me. All the best Esther Support Team

        Usefull

        I like this device pretty accurate and easy to use and clean the drawback is that it needs an app to give you a reading and it will try to charge you extra for "better" accuracy

        Right Price Accurate Take care of it.

        I bought this without knowing anything about ph meters and was happy Morebeer recommended the storage solution. As many have said mine came a bit dry and had crystals in the cap. Kind of hard to avoid if you ask me but I re-hydrated with the storage solution and then did a 3 point calibration with no problem. Immediately tested distilled water and got the expected ph and used on my first brew day since I got it and it worked well. I'm not certain the typical protocol but I found taking a small sample of the mash or boiling wort into a glass jar (not a large sample) and letting it cool just slightly was better than dunking it in boiling wort or hot mash. I'm pretty sure if you take care of this keep some storage solution in the sealed cap it will last as much as you need. I did notice that I got the very best results especially during calibration if you religiously rinse the probe with distilled water between each test.

        Works Great!

        Works great. I've had my SC-300 since 2017. The SO2 measurements were always questionable. With this new probe they are easy repeatable and believable. I probably should have returned the original probe for replacement. The new probe is great!!

        Great!

        Costly but definitely worth the confidence and efficiency in my gravity readings.

        Timothy

        Overall I think this is a great product. I am still working on really calibrating as the calibration in distilled water still leaves my higher gravity readings several points lower than my actual hydrometer when I compare the two. For monitoring the actual fermentation and temperature however this has been a very handy tool. It's great to know when your beer hits your FG!
