Product Data Sheet for Analog Output Sensors

Process Free Chlorine Sensor with Analog output A420-FCL

SKU: A420-FCL

Doc No: A420-FCL-DS-EN-10

Introduction

A420-FCL Free Chlorine Sensor is an excellent choice for continuous measurement of free (or residual) chlorine in swimming pools, spas, industrial applications, or dirty/colored samples where colorimetric methods are inadequate. This electrode utilizes 2-electrode ampero-metric measurement technology and the measured chlorine concentration is compensated by an internal temperature sensor. Analog output 4-20mA allow easily integrate into any Monitoring or Control systems.

Affordable, complete, free chlorine electrode system;

Long life with replaceable membrane and refillable electrolyte;

Auto temperature-compensated output;

1⁄2” NPT fittings for easy installation in pipe or our available flow cell;

Factory calibrated, no zero calibration required;

Analog 4-20mA output;

Plug & Play.

Typical Applications

A420-FCL can be used to monitor or control the residual chlorine in:

Swimming pools;

SPAs;

Industrial Process;

Municipal Water;

...
