can co2 control sensor for classroom testing

Suggested CO Control Sequence Of Operation

offices can generally be controlled with one sensor in the central space (up to 5000 sq ft). In office building floor plates divided up into separate suites, at least one sensor per suite is recommended. Sensor Placement: Sensors should be placed so that they can take a representative sample of CO 2 concentrations in each major occupied zone. Sensors can be placed in the space using similar ...

Identifying poorly ventilated areas and using CO2 monitors

Check that mechanical systems provide outdoor air, temperature control, or both. If a system only recirculates air and has no outdoor air supply, the area is likely to be poorly ventilated ; Identify areas that feel stuffy or smell bad ; Using carbon dioxide (CO2) monitors. People exhale carbon dioxide (CO2) when they breathe out. If there is a build-up of CO2 in an area it can indicate that ...

Suggested CO Control Sequence Of Operation

Sensors can be placed in the space using similar location criteria to thermostats. An addition consideration is that the sensor should not be in a location where people might regularly breath directly into the sensor. The TR9290 and TR9293 CO 2 sensors from AirTest are designed for wall mounting. Sensors should be placed 4-6 Feet above the floor.

CO2 sensor calibration | Edaphic Scientific

A sealed calibration enclosure, a tank of pure nitrogen, and calibration software is required to match the original factory testing environment. Otherwise, the accuracy of the calibration cannot be ensured. calibration using fresh air. Where maximum accuracy is less important than cost, a CO2 sensor can be calibrated in fresh air. Instead of calibrating at 0ppm CO2 (nitrogen), the sensor is calibrated at 400ppm CO2 …
