CO2 Traffic Light, OL0119-G2

The precise CO2 traffic light OL0119-G2 is designed for indoor use and detects changes in CO2 concentration in ppm.

A high CO2 level is an indicator of a high level of aerosols in the indoor air. They remain suspended there for a long time and form one of the main transmission routes of COVID-19. Keeping aerosol exposure low in enclosed spaces thus also reduces the risk of corona infection. Our new CO2 traffic light helps with this.

Function

The CO2 traffic light flashes brightly in the colours green (ok), yellow (critical) or red (too high), depending on the CO2 load, and helps you to initiate countermeasures such as cross-ventilation promptly. Too high a load is additionally signalled by a beep. This makes it possible to use the device in places that are difficult to see. The reliability of the OL0119-G2 is maintained even after years, as the system can continuously calibrate itself and is therefore maintenance-free.

Due to the particularly energy-efficient design, it is possible to monitor the CO2 values over a period of up to two years with only one commercially available 3.6V AA lithium primary cell. Alternatively, an external 5V/1A USB Micro-B power supply can be used. When operating with an external power supply unit, the display changes from flashing mode to continuous light!

The CO2 traffic light can be adapted to your individual needs in every aspect with the help of the PC configuration tool. This same software interface also allows the sensor to be used as a CO2 data logger! This allows you to import the recorded data into almost all data processing programs in the simplest way.
