AO-RL/A Room air quality sensor for mixed gas (VOC)

The AO-RL/A mixed gas sensor registers the air quality in the range of 0...100% with respect to the calibration gas and converts this measured value into a linear output signal 0-10 V or 4-20 mA.

As an option the air quality sensor has a potential-free changeover contact and a backlit display.

The display content can be rotated in 90° steps using a menu and the measured value, the switching threshold set, the state of the relay, the MIN/MAX measured values for the selected intervals (1 h / 6 h / 12 h / 24 h) etc. can be read out.

The sensitivity can be set on the device at “low”, “medium” and “high”.

The air quality that is defined as normal for the environment can be specified on initial start-up by manual calibration on the device (zero point balance).
The air quality sensor performs an automatic calibration at regular intervals, long-term drifts and the operational wear of the sensor element are thus totally eliminated.
