Signal light CO?

The purpose of the CO? Signal Light is to measure the level of CO? in the ambient air. 
 
Highly effective in minimizing the risk of COVID-19 transmission, the use of the CO? traffic light is highly recommended in enclosed spaces.
 
Through infrared technology, this traffic light kit alerts you if the level of CO? in the room you are in becomes significant.
 
This way, you will know when ventilation is needed, so necessary in this time of pandemic.
 
Offices, classrooms, conference rooms, stores, medical offices, restaurants, etc., are some examples of application of this traffic light kit (green/orange, red) with CO? determination.
 
Very intuitive and easy to understand, the traffic light is offered with a light column with CO? determination, with mounting material and a power supply unit for 230 V.
 
Authorized for a temperature range of -20 to +50 °C, this CO? signal light for monitoring air quality in confined spaces is manufactured with an aluminum alloy housing.
 
Very practical with its small dimensions (80 x, 80 x, 22 mm) and light weight (150 g), the CO? signal light should ideally be placed in the center of the room, less than 2 m from the floor.
 
When the green light is on, no ventilation is required. Once the red light is on, ventilation becomes necessary until it turns green again. Similarly, the yellow light requires a renewal of the ambient air.
 
Opting for this BE ATEX product means taking advantage of a recalibration of the devices, the control and verification of the I.P.E., as well as the configuration of the devices.
 
Only, in very large rooms such as an amphitheater or a sports hall, it is better to have two detectors. The rate of CO? in the air is expressed in three levels:
 
Green light: CO? level below 800 ppm. No need to ventilate the room.
Yellow light: CO? level between 800 and 2000 ppm. It is necessary to ventilate the room.
Red light: CO? level higher than 2000 ppm. It is necessary to ventilate the room or even to leave it if possible.
