Amperometric Chlorine Dioxide Electrode | GF2632

Amperometric Chlorine Dioxide Electrode | GF2632

Amperometric Chlorine Dioxide Electrode – Overview

This electrode is designed to measure residual chlorine dioxide in water treatment applications. The electrode is available with a measurement range of 0.02 to 2 ppm. This electrode requires the electrode to output a digital (S3L) signal to the 9950-X Chlorine Controller. Utilising smart-sensor technology, this electrode has a unique embedded memory chip and can communicate a wide variety of information to the 9950-X Chlorine Controller. The 9950-X can display the electrode’s stored information including the serial number, electrode type, service time in hours, chlorine range, and high and low temperatures. The patented DryLoc® connector with its gold-plated contacts and O-ring seal ensures a waterproof and reliable interconnect to the 2650 electronics. This allows quick assembly during system start-up while providing an easy way to service or replace the Amperometric electrode. This electrode is required to be in chlorinated water at ALL times.

Amperometric Chlorine Dioxide Electrode – Features

  • Embedded memory chip accessible via the GF 9950-X Chlorine Controller
  • Quick assembly with DryLoc® connector
  • Integrated temperature element for automatic temperature compensation
  • Separate drive electronics (2650 Electronics), for easy servicing & electrode replacement
