Description
Chlorine detector-transmitter E2638-Cl2 is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include swimming pools and spas, wastewater treatment plants and other areas, where potentially toxic concentration of chlorine can accumulate.
The instrument utilises a fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime.
Two relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.
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.
