  • Default alarm set-points 20 / 50 %LEL
  • 2 × 4-20 mA / 0-10 V, RS485


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.

Two relays with closing contact may be used for remote signalling or ventilation control. The default alarm set-points are typically at 20 %LEL and at 50 %LEL.

The instrument utilises novel fully calibrated and temperature compensated MOS 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.
