OPTi Digital Range – Industrial & Chemical by Bellingham & Stanley

The OPTi digital hand held refractometers are manufactured in UK as a highly reliable premium quality instrument suitable for arduous environments to be suitable for a large number of applications.

OPTi refractometers are designed using the latest manufacturing techniques, which include ultrasonic welding to bond the housings, stainless steel injection molding to construct the easy clean prism dish, and a rubberized switch membrane to further protect against moisture ingress and excess wear. The instrument may also be used for controlling dissolved solids or the blend ratios of a number of products from fresh fruit to industrial chemicals.

Single-scale and general purpose duo models for industrial and chemical applications are provided in the tables below:
