uv spectrum


The UV-Photometry is based on the absorption of radiation in the spectral range between 200nm and 400nm. In this area, some important technical gases have a pronounced absorption band. The advantage of this type of gas analysis is that the…

Oxygen Sensor

The O2sens from Wi.Tec is based on an electrochemical process. In this process, a chemical reaction takes place with the oxygen to be measured and a liquid electrolyte. In this reaction, 4 electrons are released per oxygen molecule. The resulting…

Humidity Sensor

The HUMI.sens® is based on a capacitive humidity sensor. This sensor consists of a hygroscopic polymer material in which the water vapor from the measurement gas is stored. This incorporation changes the dielectric properties of the polymer material. The polymer…
