Professional Refractometer, GoerTek Hand-held High Measuring Range Honey Tester with ATC for Strong Sugar Water Content Measurement, Replaces Homebrew Hydrometer Brix Scale Range 0~90%.

If you are expecting a laboratory grade instrument with NIST traceable standards for under 20 dollars, this is DEFINATELY the wrong item for you. If you are checking/verifying the salinity of your latest batch of fermented pickles or sauerkraut then this is exactly what you need. This is a lower range scale to check the salinity of foods. And in the lacto-fermentation world you want to verify what the salt level is in your brine. This will do it with acceptable accuracy and at a very acceptable price. I referenced it to distilled water (0%) and different w/v salt ratios and it was pretty darn close and exactly what I needed. Not bad for M.I.C too.

We were trying to get our syrup right and as a home producer didn't want to loose lots of syrup to check sugar content. We finish in the microwaveso the temperature method was not an option. Two drops that's it. You look for where the color changes from blue to white. Easily accurate to 1%. I checked some comecial maple syrup and it was 65% right on. Ours was already calibrated, which is simple. Cleanining is a snap and it comes in a nice case,with an eye dropper and a adjustment screw driver.

Could not adjust the refractometer at all may have been busted will not recommend to anyone bought this for work and turned out to be defective product !! Adjusted review ⤵️MC-Power sent me another one at no charge to me and this one works fine I just got a defective one first time around it happens but they made it right which was appreciated 👍🏼

It is simple t o use. We bought it to check tbe brix of jams we produce and it seems adaquate to that task. Calibration however is just adjusting the zero point and the set screw is hard to engage with the screw driver provided. Fortunately the zero did not need adjustment. There is no need to use distilled water to set the zero as the refractive index of tap water is so close to distilled water relative to yhat of brix of > 30%. Case latch is stiff and somewhat difficult to open. This is a minor issue

I use this to check the sugar content of sorbets to ensure good consistency of the finished dessert. This meter works well with opaque, pureed fruit -- and the price was great.

Works great for measuring sugar content when making maple syrup.

Excellent. I tried agains Cola and other drinks with stated sugar content and the result was almost same with what manufacturer was on label.Very impressive for a cheap device like this

I bought this to test the sugar content in mandarin oranges that we grow. So far, it seems to be very accurate and was easy to calibrate.
