The air quality meter is used in offices, workshops or in laboratories to carry out indicative measurements of the environmental conditions. In addition to the number of particles, the particle counter determines the mass concentration of PM2.5 and PM10 in the measuring range 0 … 1000 µg/m³. In addition, the temperature and the ambient humidity are measured. With the alarm limit function, limit values ​​for PM2.5 can be set on the particle counter.

During a measurement it is possible to record the measured values ​​with the air quality meter. A memory with a storage capacity of approx. 12 measurement runs, each with 999 measurement points, is available for the particle counter. The interval can be set at different times on the particle counter.

The 8 Wh battery can be charged via the micro USB interface. The battery used in the air quality meter enables an operating time of approx. 9 hours. Thus, the particle counter can carry out measurements over an entire working day before it has to be recharged. Since the battery is not permanently installed in the particle counter, it can be easily replaced.
