For this reason, the CO2 monitor alerts you visually and acoustically to ventilate. With the CO2 data logger function (long-term measurement) the measured values can be stored for any period of time. The collected data can then be visualized and evaluated in the software.Due to the exact measured values of CO2 levels, air temperature and humidity, the CO2 Monitor is also suitable for various other environments.Fresh air against airborne virusesGood indoor air quality guarantees a low level of pathogens in the air and the spread of airborne viruses. In a healthy indoor climate, CO2 concentrations are assumed to be below 1000 ppm. With the Wohler CDL 210 CO2 Monitor you always have a close eye on the room climate and the corresponding limit values. The adjustable alarm function reminds you of the need of fresh air. Thus the spread of airborne viruses (e.g. the corona virus) in closed rooms can be prevented.¹ only with Wohler CDL 210.
