Ahjar Safety - Draeger polytron 8200 cat flammable gas detector in Oman, Muscat

Draeger Polytron 8200 CAT Flammable Gas Detector

The Draeger Polytron 8200 CAT is an advanced explosion proof transmitter for the detection of flammable gases in the lower explosion limit (LEL). It uses a catalytic bead DraegerSensor Ex … DD, which will detect most flammable gases and vapors. Besides a 3 wire 4 to 20 mA analog output with relays, it also offers Modbus and Fieldbus protocols making it compatible with most control systems.
