The air quality data logger is excellent for continuous recording of air temperature, humidity, CO2, PM2.5, and air pressure. All these parameters provide safety professionals with information about air quality. The measurements are 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 is 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 in case of exceeding temperature, humidity, or dust concentration levels. In addition to the measurements, the air quality data logger also displays the current time.
