co2 monitor ppm

: CO2 Monitor

If you have an indoor air quality CO2 monitor that is in the ppm range, most often the unit can be calibrated to fresh outdoor air which is 413ppm. If you have a CO2 meter or analyzer with a 0100% range, typically one will calibrate in the midpoint of the range, 50% CO2 with a calibration gas bottle.

What Is the Ideal CO2 Setpoint for Demand Control ...

20190814· Enhanced DCV with Air Pollution Monitoring. Carbon dioxide must reach concentrations close to 100,000 ppm to threaten humans. This is an extremely high value, and even buildings with poor airing are unlikely to exceed 10,000 ppm (onetenth of the lethal concentration). However, other substances become dangerous at much lower levels than CO2.
