Review on 📏 Milwaukee Instruments MA871 Brix Refractometer, Digital, 0-85% Range by Maria Marshall

I work in the metal liquids industry and was trying to use this instead of a hand held refractometer. I zeroed this and the manual and in 3 out of 4 tests this differed by at least 0.5 Brix. When used on fresh clear and clear emulsions this is an average error. I have triple tested it with another brand of handheld refractometer that matched my first handheld refractometer, but this electric refractometer doesn't seem to work. Sometimes the reading is 0.5 higher, then the next sample of the same liquid is even 1.0 lower. That's too imprecise for my area. This is completely useless for milk emulsions up to +/- 3.0 Brix. I had two other lab techs test this thing and compare it to 30 coolant samples and both had horribly inconsistent results compared to doing it manually.
