Hydrogen Sulfide detector-transmitter E2648-H2S is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include sewerage systems, labs, industrial premises and other areas, where potentially toxic concentration of hydrogen sulfide can accumulate.

The instrument utilises novel fully calibrated and temperature compensated electrochemical 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.
