◆ The CO2-A / A air quality sensor records the concentration of CO2 in the air around 3 different measuring ranges (0-2000 ppm, 0-5000 ppm, 0-10000 ppm) via an infrared sensor non-dispersive (NDIR) and converts this measured value into a linear 0-10 V or 4-20 mA output signal.
◆ Protection type IP65.

► 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 (0-2000 ppm, 0-5000 ppm, 0-10000 ppm) which can be switched, according to requirements, by the innovative DIP switching technology.

► The zero point balance depending on the actual ambient conditions can be performed on the device by manual calibration. The quality sensor performs an automatic self-calibration at regular interval, thus ensuring a long-term stable CO2 measurement.

Protection type	IP65
Protection class	III
Working range r.H.	0...98% r.H. in contaminant-free, non-condensing air
Working temperature	0...+50°C
Storage temperature	-20...+50°C
Initial operation	After switch-on of the device follows a self-test and the tempering, which takes ca. 10 minutes depending on the environmental conditions. At this time the analogue output drifts from the actual measurement value.
Automatic calibration	To ensure an excellent long-term stability, in the interval of 7 days starts an automatic recalibration. This feature can be disabled on the device by DIP switch.
Manual calibration	The manual calibration of the output signal to 400 ppm (zero point) will be started by pushing the button on the circuit board (push ca. 5 s until LED is blinking). Before this it is to ensure a non-stop operating of min. 10 minutes on fresh air. After successful calibration the LED will be deactivated.
Installation	screw fastening
Approvals	CE, EAC, RoHS
