CO2 Sensor System 55 Colour Aluminium

Product code: 2381 203
The Gira ambient air sensor CO enables ambient air and therefore also well-being to be improved by monitoring CO concentration. If set limits are exceeded, e.g. windows can be opened or fans switched on, and an internal buzzer can also signify an increased level of CO concentration.

Areas of application

Whether school classrooms, meeting rooms or seminar rooms: where people are plentiful, CO concentration can build up quickly. An increased concentration of CO negatively affects well-being, the ability to concentrate and also performance, beginning with a CO concentration of just 0.08 %. The maximum value recommended by DIN 1946 of 0.1 % is often exceeded with today's building standards and the high density of building shells. In buildings like this, it is sensible to monitor the quality of the air automatically.


The Gira ambient air sensor CO measures the CO concentration in the air and indicates with a red or green illuminated LED whether it is above or below the set limit value. An upper limit value of 800 ppm to 1,500 ppm can be set. If this limit value is exceeded, a corresponding function can be activated via a 2-way relay contact, e.g. open window or switch on ventilator. The internal buzzer can also be triggered with excessive concentrations of CO. In addition, it is also possible to activate an external light such as the Gira LED signal light in order to signify the CO content and the necessity of ventilation.


The Gira ambient air sensor CO is the first on the market that can be installed flush-mounted and that matches a switch range.
