Explosive gas detector-transmitter J DITTRICH

The gas measuring systems for explosive gases and vapors made by J. Dittrich Elektronic determine the concentration of explosive gases and vapors in air in an ambient temperature from -10 to +50° C.

A pellistor or semiconductor sensor detects methane (CH4), hydrogen (H2), propane (C3H8), alcohol and benzine; additional hydrocarbons on request.

The calibration is carried out with the aid of the respective test gas by means of a potentiometer; however, a certain amount of cross-sensitivity of the sensor with regard to the other substances always remains.


Low-cost infrared measuring system for methane

Since the cross-sensitivity of the sensors gives rise to problems when monitoring methane, J. Dittrich Elektronic developed a new infrared measuring system which detects specifically methane quicker, more accurately and at less cost than conventional infrared systems.
