General Information on CnHm – Hydrocarbons
CnHm – this term covers all compounds in which carbon and hydrogen are present. The alkanes form a defined subgroup. Since the known measurement methods (NDIR, FID, PID, …) do not allow selective analysis of individual hydrocarbon compounds, a summary is always given. The weighting of the individual hydrocarbons is known for the respective measurement method.
Gas Sensors for the Detection of CnHm

- Innovative NDIR Sensor (non-dispersive infrared sensor)
- Max. 3 simultaneously detectable gases per sensor unit
- Measuring ranges from ppm to Vol.-%
RITTER »MultiGas« Combined Modules NDIR + NDUV
RITTER »MultiGas« Modules can also be a combination of both NDIR sensors and NDUV sensors on a common board. With this unit, up to 3 gas components can be measured simultaneously. The basic electronics can supply IR and UV radiation sources with different frequencies for 0 Hz (DC) to 100 Hz (AC). This system is an ideal tool for detecting multi-component gas at low ppm levels.
Please note: For technical and chemical reasons, not every combination of gases/measuring ranges can be analyzed/measured in a single or combined RITTER »MultiGas« module. As this is a rather complex topic, please do not hesitate to contact one of our gas experts first.
