Description
Carbon monoxide detector-transmitter E2638-CO is a member of the PluraSens® family of multifunctional measurement instruments.
Applications include underground parkings, boiler houses, kitchens, and other confined spaces, 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.
Analog output and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
A version with LCD monitor is available as an option.
