Our technoline WL 1030 emerged as the test winner in the Stiftung Warentest "CO2 measuring devices and traffic lights" test (published on 04.02.2021).
High CO2 levels in the air reduce concentration and performance. To improve the indoor climate and maintain health, regular and timely ventilation is recommended. According to Stiftung Warentest, the test winner "technoline WL 1030" offers accurate readings by means of a powerful NDIR gas sensor with CO2 measurement and a calibration function for personal readjustment. The technoline WL 1030 is equally suitable for private, commercial and public premises and supports a healthy indoor climate and the preservation of health with ventilation recommendations at the right time. The CO2 content in the room air is displayed by precise ppm values and supplemented by ventilation recommendations with colored indication fields in the traffic light system.
