Description
Nitrogen dioxide transmitter E2618-NO2 is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include underground parkings, boiler houses, kitchens, and other confined spaces, where potentially toxic concentration of nitrogen dioxide can accumulate.
The instrument utilises a 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.
