Review on 🔍 Enhance Precision with HunterBee Portable Refractometer Resolution Instrument by Kaushik Sokolowski

When I first got this I was excited because it was pretty cheap and easy to read. There was just one problem: it was very different when I tried testing it against some known concentrations of alcohol. "Nothing to worry about," I thought, there is a calibration screw in the device that supposedly can be used to adjust the measured values of the refractometer. Unfortunately, the screw failed to change the readings of the device, meaning I'm stuck with a useless device disabled by a large but unspecified amount. I would avoid it!
