Overview

These in-line models can be incorporated in piping of manufacturing plants, liquid mixing devices, and washing apparatuses to continuously measure the concentration of various liquids. 
They are suitable for use in the control of mixing, concentration, fermentation, and control of the concentration of water-based or alkali-based detergent, etc.

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 -30 to 165℃ (during SIP / CIP).
