Unitronic presents a sensor module with which volatile organic compounds (VOCs) in the air can be recognized very quickly and with very high accuracy thanks to a special sampling process. With the USM-VOC it is not the ohmic resistance of the gas sensor that is analyzed, as is common practice, but the electrical charge shift in the sensor element. This method not only ensures a very quick response to changes, but also enables faster recovery times. In addition, the sensor, which reacts to different volatile substances such as carbon monoxide (CO), toluene and ethanol, features an almost twice as high resolution, especially at low concentration levels, compared to the conventional resistive measurement method.
