Oxygen detector-transmitter E2638-O2 is a member of PluraSens® family of multifunctional measurement instruments.

The instrument may be used to prevent critical decrease of O2 concentration as well as to control the absence of the oxygen in gas mixtures.

The instrument utilises a fully calibrated and temperature compensated 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.
