The iPR comes with a measuring range of up to 90% Brix (refractive index 1.5200). It is suitable for almost all applications in food production and pharmaceutical industries, but it can also be used for many processes in mechanical and automotive engineering, and in chemical appliances.

ID-N° 12612 TriClamp connection
ID-N° 12613 APV connection
The special design and electronic equipment make the iPR highly flexible and easy to use. The iPR-B is equipped with two switch outputs to run, for example, a connected valve (max. 1A, 24 DC) or relay. With this feature is it also possible to control the cleaning of the measuring prism via a magnetic valve.
The iPR-B measuring head can be installed in pipes, reactors, vessels, and mixing tanks, using different weld-in flanges. Our preferred joint system is VariVent. It allows easy installation through a plug-in clamping method. Some processes may require cleaning of the sensor face. SCHMIDT + HAENSCH offers an optional cleaning nozzle or a specially designed ultrasonic cleaning device.
For determination of mixing ratio, the SCHMIDT + HAENSCH Brix refractometer can be applied in the sugar and agricultural industry, in the production of cane and beet sugar, molasses, or in biomass material characterization. These parameters are equally applied for measurements within the food and beverage industry, e.g. production of marmalade, fruit juice, and lemonade and more.
Liquid identification and distinction of materials for interfacing purposes is easily made possible with SCHMIDT + HAENSCH’s iPR-B.
The sophisticated design of the stainless-steel housing of the sensor is equipped with a blue anodized air cooling jacket. This cooling jacket protects the electronic components from overheating in process temperatures up to 90 °C (194 °F). CIP cleaning at the prescribed temperatures is possible when the instrument is switched off.
