ULTRA.sens - Model AK100 -H2S Gas Measurement Module

FromWi.Tec-Sensorik GmbH

SHARE

The ULTRA.sensis the world’s first OEM gas measurement module based on miniaturized UV LEDs. The stability and lifetime of these UV-LEDs enables high-precision gas analyses down to the ppb range. By using two UV-LEDs 2 gases can be detected simultaneously. With this approach, 2 measuring ranges from ppm to Vol.-% can also be realized. In the spectral range from 200 nm to 500 nm, nitrogen oxides (NO+NO₂), aromatic hydrocarbons, hydrogen sulphide, ozone, sulphur dioxide and chlorine can be reliably detected with this novel sensor platform.
