High CO2 levels in school classrooms continue to be a concern. As a result we reviewed the massbalance model of ventilation. We identified several factors by fitting the model to the data.
20121017· It has also been shown that high school CO2 levels can negatively affect student health and lower attendance rates. Aretas Sensor Networks designs and builds a variety of indoor air monitors, including a wireless carbon dioxide (CO2) monitor.
Such devices can also include the facility to isolate the gas in the event of a high CO2 level or ventilationfan failure. A gas pressure proving system for use in a teaching area should be fitted with an emergency gasisolation button on the panel, as well as a key switch to control gas availability at workbenches. A countdown timer should also be incorporated, to ensure that gas is not ...
20210428· 20210428· The graph below is from a typical classroom air handling unit (from Vimy Ridge Public School, taken in April 2021). The 1day trend of CO2 levels shows that during our purge cycles (before and after school) the CO2 levels are consistently at 450 ppm, or the same as the outdoor air. During classroom hours the CO2 levels rise but are kept in the 650750 ppm range because of …
Thousands of AirTest CO2 sensors have been installation in school districts throughout the US and Canada. AirTest is known for its zero maintenance, selfcalibrating sensor. If you are involved in a school project and would like to talk to another district or contractor who has used AirTest CO2 in their project please contact AirTest at 604 5173888 to for references.

Neulog''s CO2 sensor is based on an electromechanical reaction between CO2 gas and the sensor. The result of the electromechanical reaction is voltage, measured by the logger sensor. The measure units are ppm (parts of CO2 per million of air). Note: The sensor must be calibrated before every use according to the following simple procedure: connect the sensor to the PC through a USB module or a ...

20140113· 20140113· Carbon dioxide levels in the classroom have been shown to be directly related to a students alertness and ability to concentrate. High levels of carbon dioxide indicate a lack of fresh air intake and that negatively affects the health, attendance rate and learning ability of students. “Increases in indoor CO 2 concentrations… were associated with statistically significant and …
The Company has also had RFP''s (Requests for Proposals) from a number of OEM customers for carbon dioxide (CO 2) sensors in school classrooms to verify ventilation requirements of COVID19 protocols. "You can''t manage what you don''t measure" is a mantra that has great application in relation to COVID19. Elevating the outside air ventilation levels going to indoor spaces is crucial in limiting ...
20210213· Funny boxes have appeared in school and university classrooms, and they could well multiply while SARSCoV2 is still circulating at a high level in France. These CO2 sensors are used to measure air quality. An indicator light comes on when it gets too bad. Ultimately, the goal is to limit the risk of transmission of Covid19.
