Atago 3575 In-Line Brix and Refractive Index Concentration Refractometer, PRM-TANKα, Brix : 0.00 to 85.00%, Refractive index (nD) : 1.31700 to 1.51000 Measurement Range

Not rated yet


Directly connects to a tank.  Real-time measurement of the tank's internal concentration.

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.
