All-purpose Refractometer – PR23GP

 

kpatentsAn all-purpose refractometer for large pipe and vessel installations. Installation through a flange or a clamp connection. Area classification Zone 2 (Class I, Div. 2); Intrinsically safe process refractometer PR-23-GP-IA Area classification Zone 0 and Zone 1.

Helps to control the concentration and to assure the critical product quality attributes. The batch time and quality can be optimised, and timely and costly sampling can be reduced.

Digital sensing technology, even large amounts of suspended solids, bubbles or colour changes do not affect the measurement or the accuracy.
