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-100α

The unit measures the refraction of light generated between the prism surface and a liquid sample. The PRM-100α 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.

PRM-TANKα Process Refractometer

The PRM-TANKα Process Refractometer features a new design of the detection unit, which is to be mounted on the wall of a vessel. It is ideal for a variety of vessel types, such as distillers, condensers, blenders, fermenters, extractors, and filtration tanks. The flat sample stage prevents sample buildups, keeping the prism clean over an extended period of time.
