A/CO2-DC

The A/CO2-DC series monitors carbon dioxide (CO2) levels in industrial and living environments from 0 to 2000 ppm. It has a dual-channel optical system which allows it to be used in applications where there is full-time occupation 24 hours a day.

The dual channel sensor performs periodic self-calibrations using the reference channel. The self-calibrations occur approximately once every 24 hours and will take approximately two minutes. To maintain the hightest application accuracy, it is recommended to periodically field calibrate using nitrogen gas, or an alternatively ambient calibration.

This series offers the flexibility of adding analog relative humidity and temperature sensor outputs in a single wall-monted enclosure. It also offers multiple analog outputs of 4-20mA, 0-5VDC, and 0-10VDC. The LCD is available for certain models.
