The air quality data logger PCE-AQD 20 is an ideal measuring device for monitoring the air quality at workplaces. The air quality data logger 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.
The format is XLS, so the measured values can be read directly into Excel, without having to be incorporated into a new software. The measured values are displayed on the large, illuminated display. The air quality data logger is operated by batteries or 9 V power supply unit. As a special feature, this air quality data logger is equipped with an alarm function. This offers the possibility to inform the user about an exceeding of temperature, air humidity or dust load. In addition to the measured values, the air quality data logger also informs about the current time.
