Description
Hydrogen Sulfide transmitter E2618-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.
The instrument utilises a fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime.
wo 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.
