PRM-TANKα

top

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.
