In-line Refractometer

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.

In-line Refractometer PRM-100a

The unit measures the refraction of light generated between the prism surface and a liquid sample. The PRM-100a is upgraded from the PRM-85 in the following aspects:

Wider than ever 0.0 to 100.00% Brix range
Improved measurement accuracy: Brix ±0.05%, nD ±0.00010
Two options for setting the minimum indication decimal place
Simple two-piece construction: detection section and operation display section
Easy-to-read color display panel.

Simply attach the unit to a piping system to monitor food or beverage production, pharmaceutical production, industrial fluid, washing devices, dilution/mixing devices, etc. Continuously monitor water content and mixing ratio with successive measurements of refractive index, Brix, or concentration.

*The prism is specially designed to prevent solid materials from collecting on the surface, even after extended periods of use.
