CO2 measuring device


Appareil de mesure CO2 pour professionnelsThis measuring device provides you with real-time information about the exact level of carbon dioxide (CO2) in a room.

  • Remote digital display
  • Wall attachment
  • Displays the level of CO2, temperature, humidity level
  • Audible alarm when the threshold limit is exceeded, can be switched on and off
  • Warranty: 2 years



This device is ideal for professionals wanting to anticipate the decree on air quality monitoring that will take effect in January 2018. This decree requires that community structures for children under the age of six monitor levels of benzene, formaldehyde and CO2.

According to the National Association for the Preservation and Improvement of Air Quality, air contains 0.04% CO2 on average. From a certain concentration in air, this gas can be hazardous and even fatal. The exposure limit value is 3% over a maximum period of 15 minutes. This threshold should never be exceeded. Above it, the health effects become more serious as the concentration of CO2 increases:

  • At 2% CO2 in air, respiratory amplitude and difficulties increase.
  • At 4%, respiratory rate increases.
  • At 10%, there may be visual disturbances, tremors and sweating.
  • At 15%, there is sudden loss of consciousness.
  • At 25%, respiratory arrest leads to death.


A high concentration of CO2 over a long period of time can cause multiple symptoms harmful to the room’s occupants: lack of concentration, fatigue, irritation, headaches, etc. According to the French Agency for Food, Environmental and Occupational Health & Safety (ANSES), the regulatory limit values for CO2 concentrations in France and internationally range from 1000 to 1500 ppm.

  • CO2 concentration display: 3 levels:Low – Intermediate – High
  • The alarm, which can be switched on and off, quickly alerts the people in the room if the level of CO2 is too high.


Useful tip: immediately ventilate the room in order to reduce the concentration of carbon dioxide.
