Hydrogen Sulfide Detector
Hydrogen Sulfide detector E2608-H2S is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include sewerage systems, labs, industrial premises and other confined spaces, where potentially toxic concentration of hydrogen sulfide can accumulate.
Two relays with closing contact may be used for remote signalling or ventilation control. The default alarm set-points are typically at 10 ppm and at 20 ppm H2S.
The instrument utilises novel fully calibrated and temperature compensated 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.
