This meter has a large LCD display showing CO2 (carbon dioxide) and temperature simultaneously. This meter uses NDIR (Non-dispersive infrared) waveguide technology in its CO2 sensor. ABC (automatic background calibration) is also used for long time drift compensation. This meter has an alarm output that drives the built-in relay function to control the ventilation systems. The meter displays a TWA (time-weighted average) value of the past 8 hrs or a STEL (short term exposure limit) value from the past 15 minutes. The meter is also easy to calibrate using CO2 in the fresh air.
