Technical specifications
General describtion:
A stationary gas detection system consists of a detector (transmitter) and a central controller. The detector
and the controller are connected with a cable. The detector converts gas concentration into an electric
measurement signal and transmits it via the cable for processing to the controller.
Gas detectors GS-300.A/GS-300.N are intended for detection of explosive and toxic gases. They are
suitable for detection of different gases depending on gas detection element.
Measuring method:
The following mesuring methods are used:
1.Cathalityc sensors for mesurement of explosive gases.
2.Electrochemical sensors for toxic gases.
3.Infrared sensors for CO2.
4.Semiconductor sensors for refrigerant gases.
