Measured values can be recorded with the data logger function of the air quality meter. The large memory of 32,000 measuring points in the air quality meter allows recording of measured values over a long period of time. After data logging, all logged measuring points can be read out and analyzed via the micro-USB interface of the air quality meter and the free software. The data logged by the air quality meter can be exported in CSV file format for further processing.
A 3.7 V Li-ion battery is installed in the air quality meter to enable mobile use. This battery can be recharged via the micro-USB interface on the air quality meter.
