General Information on H2S – Hydrogen sulfide
Hydrogen sulfide (H2S) (also dihydrogen sulfide) is a malodorous, colorless, highly toxic gas. It is corrosive, flammable, highly combustible, and slightly heavier than air. It is slightly soluble in water and slightly more soluble in ethanol. H2S is a very weak acid whose salts are the sulfides and hydrogen sulfides. Even in very low concentrations, hydrogen sulfide can be recognized by its typical rotten egg smell. It is formed, among other things, during the decomposition of sulfur-containing amino acids in biogas plants with concentrations of up to 10,000 ppm.
Gas Sensors for the Detection of H2S
- Innovative NDUV Sensor (non-dispersive ultraviolet sensor)
- Max. 2 simultaneously detectable gases per sensor unit
- Measuring ranges from ppm to Vol.-%
- NDUV Sensor (non-dispersive ultraviolet sensor) / Dual beam
- Max. 2 simultaneously detectable gases per sensor unit
- Interference-free measurements with water vapour and hydrocarbons
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.
