Description

Carbon monoxide transmitter E2638-CO is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include underground parkings, boiler houses, kitchens, and other areas, where potentially toxic concentration of carbon monoxide 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.

Two relays with closing contact (option) may be used for remote signalling or ventilation control. Default alarm set-points are 25 and 35 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.
