The air quality data logger is excellent for the continuous recording of air temperature, humidity, CO2, PM2.5, and air pressure. All these parameters provide the safety professional with information about air quality. The measurement data is stored on an SD memory card. The format is XLS, allowing the data to be directly imported into Excel without the need to familiarize oneself with new software. The measurements are displayed on a large, illuminated screen. The air quality data logger can be powered by batteries or a 9V plug power supply. A special feature of this air quality data logger is its alarm function, which notifies the user when temperature, humidity, or dust levels exceed set thresholds. In addition to the measurement data, the air quality data logger also displays the current time.
