Description
ADS-VOC is space gaseous air pollutants sensor with analog voltage output 0-10V and output relays with adjustable levels of switching. The sensor is based on a semiconductor sensing element. It changes its conductivity in dependence on the air contamination. Built-in electronics converts the input conductivity changes to the 0-10V analog output. The sensor has a high sensitivity at low concentrations of pollutants in the air such as ammonium and hydrogen sulfide produced during decomposition of organic waste materials. It is suitable for ventilating room’s contaminated gaseous substances of organic origin, cooking fumes, cigarette smoke and etc.

| (1) For the long term stability it is recommended to power the sensor continuously. | ||
| (2) Since power on to warm-up the sensor. The first 10 minutes the output will be 0V. The relay starts to switch after this interval. In the next 24 hours the sensor will stabilize. | ||
