| The Dräger Polytron GD30R is an intrinsically safe open path gas detector used for continuous monitoring of hydrocarbon gases in ambient air. |
|
| The system, suitable for indoor applications, uses microcontroller technology to convert an infrared signal to a 4 to 20mA analogue output from the Receiver unit. This signal is proportional to the quantity of gas present in the beam path. |
|
| The system comprises of a separate Transceiver unit and reflector panel and has an operating distance from 6 to 30 metres. The GD30R is factory calibrated for either Methane or Propane. An alignment module is supplied with the device which enables one-man commissioning to be carried out easily. |
