Gira CO²-sensor

Gira CO²-sensor,
E2, pure white glossy
The Gira CO²-sensor enables ambient air and therefore also well-being to be improved by monitoring the CO² concentration. The quality of air is displayed via LED in traffic light colours. 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 CO² concentration.

Whether school classrooms, meeting rooms or seminar rooms: where people are plentiful, CO² concentration can quickly build up because everyone exhales carbon dioxide into the air. An increased concentration of CO² negatively affects well-being, the ability to concentrate and also performance, beginning with a CO² 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 such buildings, it makes sense to automatically monitor the quality of air and if necessary to influence concentration of carbon dioxide for example by opening a window or activating a ventilator.

The Gira CO²-sensor measures the CO² content in the air within a range of 0 ppm to 2000 ppm (0.2 %), displaying this via a three-colour LED display in traffic light colours. An upper limit value of 1000 ppm to 1500 ppm (0.2 %) 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 CO². In addition, it is also possible to activate an external light such as the Gira LED signal light in order to signify the CO² content and the necessity of ventilation. In this way clarity is achieved even at a greater distance from the device.

The operating elements to switch off the buzzer and set the upper limit are located hidden behind the cover plate. The Gira CO²-sensor is the first on the market that can be installed flush-mounted and that matches a switch range.
