In-line sensors

Valmet Brightness Measurement (Valmet Cormec5 X) exposes the latest developments of the optical in-line measurement technology.

In chlorine dioxide stages, it is important to measure the total chlorine including chlorite. The Valmet Filtrate Residual Measurement (Valmet Polarox5 F) sensor can measure chlorite shortly after chemical addition. 

The measurement concept designed in Valmet Peroxide Residual Measurement (Valmet Polarox5 FP) utilizes the proven method, in a new innovative way: it measures both total peroxide residual and OOH– ion residual and thus reveals more intimate information of the process conditions. 

Residual sensor for pulp bleaching applications Valmet Residual Measurement (Valmet Polarox5) is the fifth generation of Valmet’s inline sensors for pulp bleaching.
