The Gas Detector / Gas Detection Instrument is specially designed for long-term monitoring of climatic conditions in, for example, offices, classrooms or lecture halls. The Gas Detector / Gas Detection Instrument has various sensors. Among other things, the Gas Detector / Gas Detection Instrument has a carbon dioxide sensor up to 40,000 ppm, a temperature sensor with a measuring range between 0 ... 50 °C, an ambient humidity sensor with a measuring range between 0 ... 100% RH and a barometer with a measuring range between 300 ... 2000 hPa. The Gas Detector / Gas Detection Instrument can therefore be used in many applications due to its large number of sensors. The measured values ​​are shown directly on the e-paper display of the air quality measuring device. A good / medium / bad rating of the carbon dioxide content in the ambient air is also displayed.

During the measurement, the Gas Detector / Gas Detection Instrument can automatically record the measured values. The measured values ​​are saved as .csv on the micro SD card. This means that the measurement data recorded by the Gas Detector / Gas Detection Instrument can be imported directly into the company's own database. The measurement data from the air quality measuring device can be displayed in graphical and tabular form via the software.

The Gas Detector / Gas Detection Instrument has an alarm function. This alarm mode can be used to set limit values ​​for the individual sensors. As soon as the set threshold value is reached in the Gas Detector / Gas Detection Instrument, this is indicated acoustically and visually via the alarm LED. After the Gas Detector / Gas Detection Instrument falls below the threshold value again, the alarm switches off again automatically.

The measured values ​​are displayed numerically on the 2.7" display of the Gas Detector / Gas Detection Instrument. For a better analysis of the last measured values, the display can be switched to a histogram display. The energy-saving e-paper display enables a long battery life for the Gas Detector / Gas Detection Instrument. Depending on the setting the battery can operate the Gas Detector / Gas Detection Instrument for about 10 months before it has to be recharged. In addition to the possible power supply via the built-in battery, the air quality measuring device can also be operated continuously via the micro USB charging cable.
