2) Which tools are used to measure the CO2 gas which is been captured?

Answer 1

1) Which tools are used to measure the CO2 concentrations present in air?

1. IR sensors (A carbon dioxide sensor or CO2 sensor), Infrared gas sensors (NDIR).
2. Chemical gas sensors
3. pulsing laser detectors (laser induced differential absorption radar, or LIDAR)

and chemical gas sensors are the most prevalent principles for CO2 sensors.

2) Which tools are used to measure the CO2 gas which is been captured?

Nondispersive Infrared (NDIR) CO2 Sensors
