General Information on H2O – Water Vapor
In common parlance, water vapor (H2O) is usually understood to mean the visible vapor clouds of condensed water vapor (wet vapor). Vapor plumes are visible because microscopic droplets (aerosols) have formed, as in clouds and in fog. In technology and natural science, steam is the term for water in its gaseous state of aggregation. The content (concentration) is also referred to as humidity and is expressed in % relative humidity, absolute humidity (mg/m3) or vol.-% or ppm.
Exhaust gases containing water vapor condense to form white exhaust gas plumes, i.e. »steam« escapes from the chimney. Soot-containing black or gray exhaust gases, on the other hand, are referred to as smoke.
Gas Sensors for the Detection of H2O
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.
