MOX gas sensor elements of GGS series - Types and detectable gases

Our MOX gas sensor elements will be pre-aged and selected regarding sensitivity and basic resistance R_S0 of the sensitive layer. Physical and chemical limitations relating to the influence of basic resistance and sensitivity apply.
To select the most suitable sensor for a given application the following criteria apply:

• Type of sensor / type of gas sensitive layer
• Sensor design / dimensions / case 
• Classes of heater resistance
• Type/s of gas/es to be measured
• Accuracy requirements
• Ambient media and conditions.

Detailed options:
Type of sensor element	GGS	1	4	3	0	T
	GGS	Single gas sensor element
	DGS	Double gas sensor element
Sensor/ layer type	GGS	1	4	3	0	T
		1	GGS 1000				Universal sensor for various applications, especially usable for leak detection of combustible gases.
		2	GGS 2000				Sensor with a high sensitivity to CO (carbon monoxide), H2 (hydrogen) and C2H5OH (ethanol), low cross sensitivity to CH4 (methane).
		3	GGS 3000				Sensor for the detection of hydrocarbonates, optimal for C1-8-hydrocarbonates, especially usable for stationary LEL-monitoring (LEL... Lower Explosive Limit).
		4	GGS 4000				Sensor for NH3 (ammonia), low cross sensitivity to CH4 (methane), CO (carbon monoxide) and H2 (hydrogen).
		5	GGS 5000				Sensor especially sensitive to NO2 (nitrogen dioxide) and O3 (ozone).
		6	GGS 6000				Sensor for the detection of H2 (hydrogen), low cross sensitivity to CH4 (methane), CO (carbon monoxid) and alcohol.
		7	GGS 7000				Sensor for the detection of NO (nitrogen monoxide).
		8	GGS 8000				Sensor for the detection of C2H5OH (ethanol), low cross sensitivity to CH4 (methane), CO (carbon monoxide) and H2 (hydrogen).
		9	GGS 9000				Sensor for R134a and other refrigerants.
		10	GGS 10000				Sensor for the detection of selected VOCs (air components) in the trace range, usable e.g. for air quality monitoring.

Subject to alterations for this information and technological changes.

Any contamination of the sensor must be avoided. The application, transport and storage environment has to be free of any contamination, particularly protected against chemical substances, e.g. silicones.

In particular directly contact with substances containing, silicones, sulfurous substances or non-desorbing components or contaminations (e.g. smoke, fumes, oils, greases or evaporating liquids) may cause damaging the sensor or to changes in the sensor resistance and/or in the sensor characteristics.
