The air humidity meter is used to continuously measure the particulate matter content at the workplace. The air humidity meter displays PM2.5 particulate matter as well as temperature and humidity on the display. The measuring range of the air humidity meter ranges from 0 ... 500 μg / m³ PM2.5. This makes the air humidity meter an optimal test instrument to constantly have an overview of the fine dust content. Below the large measured value display of the air humidity meter content, the air humidity meter provides quick information about the air quality with the aid of pictograms.

The air humidity meter is powered by a rechargeable battery. The LC display is illuminated and easy to read from any angle, for example when the meter is on a desk. In addition to the standard white lighting, the air humidity meter switches the lighting to red in the event of an alarm.
