DPD Amperometric TCCA Free Chlorine Controller For Freshwater

DPD Amperometric Free Chlorine Controller Based On TCCA For Freshwater

Brief Introduction

DRFN's online free chlorine controller is used for the measurement of free chlorine based on isocyanic acid. It uses DPD-1 method to determine the residual chlorine value by isocyanuric acid concentration.

Advantages Of The Free Chlorine Controller
