Chlorine Detector-Transmitter

  • Stable long-life electochemical cell
  • Range 0...10 ppm Cl2
  • Resoluton 0,1 ppm Cl2
  • Attached or remote sensor
  • 2 × 4-20 mA / 0-10 V, RS485
  • Two SPST relays


Chlorine detector-transmitter E2638R-Cl2 is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include swimming pools and spas, wastewarer treatment plants and other areas, where potentially toxic concentration of chlorine  can accumulate.

The instrument utilises novel fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime.

Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.

Two relays with closing contact may be used for remote signaling or ventilation control. The default alarm set-points are typically at 0,5 ppm and at 1 ppm. The flashing LEDs and an internal buzzer give alarms as well at two set-points.
