This versatile Temperature Data Logger / Temperature Logger enables seamless and highly precise monitoring of indoor climate conditions as well as potential pollutant exposure indoors. The device measures not only classic parameters such as temperature and relative humidity, but also the general air quality index (AQI) and critical gaseous pollutants, including CO2, CO, TVOC, HCHO and C6H6. In addition, the modern Temperature Data Logger / Temperature Logger offers differentiated particle measurement, breaking down fine dust in six different size classes from PM 0.3 to PM 10 in detail.

A clear, colour-coded display ensures quick and intuitive orientation in everyday use. The respective measured values are automatically classified based on the current level of exposure: from green for excellent air quality, through yellow and orange, to red, which signals an acute hazard. This visual warning system makes it possible to react immediately to poor air conditions and initiate targeted ventilation measures, allowing the 18-in-1 Air Quality Detector to be used optimally as a safety monitor.

Thanks to the integrated rechargeable battery, the compact Temperature Data Logger / Temperature Logger can be used flexibly and is not tied to a permanent power source, making spontaneous spot checks at changing locations easier. For further documentation and long-term analysis, the collected measurement data can be transferred easily to a computer in .txt format via the modern USB-C interface. There, the values can be exported and evaluated in order to provide lasting proof of the effectiveness of air purification concepts.
