Description

Methane detector-transmitter E2608-CH4 is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include underground parkings, boiler houses, kitchens, and other confined spaces, where potentially explosive concentration of methane can accumulate.

The instrument utilises a fully calibrated metal-oxide semiconductor gas sensor with excellent repeatability, stability and long lifetime.

Two relays with closing contact may be used for remote signalling or ventilation 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.
