RET-5533 PeakAsh

RET-5533 PeakAsh

Optical sensor

The RET-5533 PeakAsh measures total consistency 0.01% to 2% and ash consistency from 0.01% to 0.7% in pulp suspensions in the range. It can be calibrated to secure stable and accurate ash consistency based on laboratory ash determination. Ash and total consistency values are independent of variation in pulp brightness or color.
