Product Features of XHV-DFR Dynamic Retention Analyzer

As the DFR water filter meter measures, the water filtration performance is continuously tracked throughout the entire measurement time.

The system boasts high measurement sensitivity, capable of detecting even subtle changes in interference parameters. With a measurement accuracy of approximately 0.6%—superior to conventional methods—it can instantly record and display the efficacy of chemical filter aids. DFR

The software provides a variety of analyses of the final results.

Function:

Measure pulp water filtration performance
■ Total retention rate and one-way retention rate of measuring paper
■ Test the effect of retention and filtration chemicals
Analysis of the role of filler and raw material
Optimize the amount of retention aid, filter aid and filler
