S18-A Residual Chlorine Sensor

Introduction

S18-A online residual chlorine sensor adopts polarographic residual chlorine electrode, measuring residual chlorine concentration after automatic temperature compensation with RS485, current 4-20mA or voltage 0-5V output. It can be widely used in water pipe network, water purification plant, hospital, swimming pool and other application places.

Characteristics

 Automatic temperature compensation;

 RS485 output, standard Mod-bus protocol;

 Fast measurement speed, real on-time measuring;

 No secondary pollution, no need for chemical reagents;

 Low maintenance cost, only need to replace the membrane cap, electrolyte and other few low-cost accessories;
