0-10% Brix Refractometer with ATC Low-Concentrated Sugar Content Solutions Accuracy 0.1% Maple Sap Cutting Liquid CNC Maple Syrup Makers Tea

A good product well packaged in a plastic case with 2 pipettes, cloth, instructions and screw driver. Very easy to calibrate, I have yet to test on sugar or beer wort solutions.Easy to use and to clean and far less likely to stir up sediment than high volume type hydrometers.

I am very happy with the product. I thought the refractometers are difficult to use, but it was not the case. It comes with all the necessary tools and English instructions.

Arrived quickly and really simple to use. I have previously used a hydrometer and sometimes I struggled to see the reading dependant of what was floating on the top of the liquid. It’s all in the past now as this provides a clear easy to read scale.

Cheap and cheerful, I've checked this against my hydrometer and it seems accurate enough. I've even used used it with alcohol present and use the conversion tables and it still seem to give accurate results when compared to my hydrometer, very happy.

Super easy to use and understand, particularly after I found and read the instructions. I use for both bear and kombucha

Service was second to none and the refractometer is absolutely just what I wanted !You can’t beat the price either !Really good value, soooo pleased I got this one.

Measured my wort OG at 1.068 with my trusty hydrometer. Thought I'd purchase this refractometer to avoid fuss/mess/wastage involved with hydrometer, and hopefully get a more accurate reading. Arrived quickly. Calibrated with distilled water, placed a drop of wort on the glass, no air bubbles, and waited for temperatures to equalise as per the instructions. Got a reading of 1.035. Thought strange as the fermentation looked to be finished. Tested with hydrometer and got 1.010. Tested the next day and got exactly the same respective readings. I’d expect readings between the two methods may not be exactly the same, but 0.025 difference is unacceptable IMO. Emailed Gainexpress to query. They replied quickly (which was good of them) and received the following reply:‘We have received an answer from the factory. The glass hydrometer's principle is the buoyancy of liquids. While the principle of the refractometer is the refraction of light. It is impossible that these 2 different meters can have the same readings and the readings must not be compared.'Hmmm...Enough said! I'll be returning the refractometer for a refund.

Perfect, easy to use.

Works perfectly and you can't beat the price.

Easy to use and clean. Very basic
