Review on AMTAST Digital Refractometer Cutting Testing: A Powerful Tool for Precise Testing and Analysis by Jerry Amos

Revainrating 1 out of 5

Do not do this for testing, measuring and verifying

The product was very variable and could not be calibrated. The first reading seemed correct, but kept repeating the same number, trying to recalibrate and doing the same thing: 1 correct reading, essentially a screen freeze.

Pros
  • Can be washed under running water
Cons
  • Not durable
