RET-5503 PeakAsh

RET-5503 PeakAsh


The RET-5503 PeakAsh analyzer measures total consistency from 0.01% to 2% and ash consistency from 0.01% to 0.7% in pulp suspensions. 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.
