FAQ:
Q: What does carbon dioxide sensor do?
A: A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO2 sensors are infrared gas sensors ( NDIR ) and chemical gas sensors.
Q: How does a NDIR CO2 sensor work?
A: Non-Dispersive Infrared (NDIR) Sensors. Simply put,NDIR sensors use specific wavelengths of light to measure the amount of CO2 in the air. … Electrochemical Sensors. … Metal Oxide Semiconductor (MOS) Sensors. …
Q: What is a carbon dioxide sensor?
A: A carbon dioxide (CO2) sensor is a small instrument that can detect and measure carbon dioxide within the surrounding air. Measuring CO2 is vital for those who work indoors or in confined spaces.
Q: What is a CO2 probe?
A: Carbon dioxide (CO2) is a colorless and odorless gas that can only be detected with a measuring instrument and which is deadly in high concentrations. Rotronic CO2 transmitters are equipped with sensitive probes and are ideal for the demanding monitoring of indoor air.
