The air quality sensor CO-A/A registers the CO concentration in the air in the environment in the range of 0-1000 ppm via an electro-chemical sensor and converts this measured value into a linear output signal 0-10 V respectively. 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. 3 different measuring ranges can be selected 0-200 ppm, 0-500 ppm, 0-1000 ppm which can be switched, according to requirements, by the innovative DIP switching technology.
