PCE Instruments AQD 20 CO2 Datalogger Analyzer

Model # AQD 20

The air quality data logger is an ideal measuring device for monitoring the air quality at workplaces.
It is ideal for continuous logging of air temperature, humidity, CO2, PM2.5 and air pressure. All these parameters give the occupational safety expert information about the air quality.
The measured values are stored by the CO2 air quality data logger on an SD memory card and the format is XLS, so the measured values can be read directly into Excel, without having to be incorporated into a new software.
