iPR FS
Inline Process Refractometer with Certified Hygienic Design
The EHEDG (European Hygienic Engineering and Design Group) certified iPR FS comes with a measuring range of up to 85 Brix (refractive index 1.5200) and is EHEDG certified making it suitable for almost all applications in food and beverage production. Available with VariVent or APV connection.
The unique hygienic design makes the iPR FS ideal for food and beverage industry applications. The measuring head can be installed in pipes, reactors, vessels, and mixing tanks, using different weld-in flanges. The VariVent joint system allows easy installation with a plug-in clamping method.
An optional cleaning nozzle or an ultrasonic cleaning device is available for processes requiring the sensor face cleaning. The iPR FS is equipped with two switch outputs to run a connected valve (max. 1A, 24 DC) or relay making it possible to control the cleaning of the measuring prism via a magnetic valve.
