In-line Refractometers PRM-2000α


Introducing An Ideal In-line Unit for Low Concentration Samples

Featuring a Brix range of 0 to 20%, with a high accuracy of ±0.050%, our newest in-line unit, the PRM-2000α is ideal for precision measurement of low concentration samples, as well as fruit juices and other beverages. Moreover, the PRM-2000α has an even higher accuracy of ±0.007% for samples with a low Brix range of 0.000 to 2.000%. The detection section is able to withstand temperatures between -35 to 165℃ (during SIP / CIP).
