Description
Nitrous oxide detector-transmitter E2638-N2O is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include electronics manufacturing, food industry, medicine and other confined spaces, where high concentration of nitrous oxide can accumulate.
The instrument utilises fully calibrated and temperature compensated optical NDIR 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.
