Review on πŸ”¬ Hanna Instruments Digital Refractometer Analysis: Precise Measurement for Quality Testing by Charles Salgado

Revainrating 5 out of 5

HI 96801 Digital Refractometer

I was skeptical but it works as it should. You'll need to calibrate it every time you use it and make sure you give it a good clean between rehearsals by pressing the Read button until it reads 0 again, rather than just resetting it to zero. But the whole process takes no more than a few seconds, at most a few minutes if you are not in a hurry or the measured sample was too thick and/or sticky. I just love it for its simplicity and the fact that it takes the guesswork out of optical blocks.

Pros
  • Weight
