Description

  Ozone transmitter E2638-O3 is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include swimming pools and spas, food factories, places where desinfection or bleaching is performed, and other areas, where potentially toxic concentration of ozone  can accumulate. 

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

To connect the detector to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol. We recommend to set the output scale within 20-100% of the detection range.

Two relays with closing contact (option) may be used for remote signalling or ventilation control. Default alarm set-points are 0,3 ppm and 1 ppm. 

The device is available with either attached or remote sensor probe (default cable length is 3 m).

A version with an LCD indicator is available.
