The Air Quality Meter is a versatile device for monitoring the air quality in indoor spaces such as homes, offices, workshops, schools or public facilities. It is used for the simultaneous measurement of formaldehyde (HCHO), volatile organic compounds (TVOC), ambient temperature and relative humidity. The Air Quality Meter has a 2.8-inch color display that shows all measured values in real time and also visually assesses the air quality in three stages - green for "good", yellow for "poor" and red for "very poor". The Air Quality Meter also has an acoustic alarm function with adjustable threshold values and sound types, which is triggered when defined measured values are exceeded.

For data storage, the device offers space for up to 200 measuring points on 5 pages, which corresponds to a total capacity of 1000 measurements per measured variable. The values for formaldehyde, TVOC and temperature are stored. The storage intervals and the number of collection points can be set individually, whereby the stored data can only be retrieved at any time via a playback function in the device. Other functions include a real-time clock, battery status display, adjustable measuring rate, automatic switch-off time, adjustable screen brightness and the option of active fan control. The temperature unit can be switched between Celsius and Fahrenheit.

The Air Quality Meter is powered by an integrated 3.7V Li-Po battery and charged via a USB type C cable. The charge status is shown on the display during operation and charging. As a compact, precise and easy-to-use Air Quality Meter, the Air Quality Meter is ideal for continuously monitoring indoor air quality and helps to detect potential exposure to pollutants such as formaldehyde or organic vapors at an early stage and take appropriate countermeasures.
