The Amprobe CO2-100 handheld carbon dioxide meter provides instant feedback for indoor CO2 levels as well as temperature and humidity measurements. Designed to measure air quality compliance in occupied spaces such as offices, production floors, schools or hospitals, the CO2-100 includes a built-in audible alarm with adjustable threshold setting to warn against dangerous CO2 levels.

Amprobe CO2-100 handheld carbon dioxide meters measure carbon dioxide levels up to 9999 ppm with an accuracy of ±30 ppm ±5% of reading. The meter features a triple display with simultaneous CO2, temperature and relative humidity readings. There is also a selectable display of dew point and wet bulb temperature. The air quality analysis has two displays that include a TWA (time-weighted average) for an eight hour time period or a 15 minute STEL (short-term exposure limit) value.

The Amprobe CO2-100 meter utilizes a high performance, low-drift sensor designed with NDIR (non-dispersive infrared) waveguide technology. The meter can be manually calibrated and has a large easy-to-read LCD display, with a backlight function helpful for reading data in dimly lit areas. Other functions include data hold, minimum, maximum and average.
