Explosion proof gas detector for continous monitoring of combustible gases and vapours in the ambient air

The Dräger Polytron IR 334 is an explosion proof gas detector for continous monitoring of combustible gases and vapours in the ambient air. The transmitter is built for the harsh offshore environment (SS316 enclosure) and it features extreme reliability. SIL 2 systems can easily be designed with the Dräger Polytron IR 334, as it contributes only marginally to the total PFD-value of a complete SIL 2 system.

The unit is designed for one-man calibration, and offers a variety of diagnostics and self test functions. The configuration and calibration of the transmitter is menu guided and easy to perform, using a HART hand held terminal.
