CO₂ Zero Calibration Kit for the Guardian NG

The Zero Calibration Kit acts as a convenient alternative to bottled gas for checking zero offsets and if necessary, zero calibration. It works by removing the CO₂from the air being drawn into the instrument, providing a cost effective alternative to nitrogen or other zero gas from a cylinder.

The Zero Calibration Kit is compatible with all CO₂versions of the Guardian NG. Zero checking increases confidence in the validity of the calibration and helps avoid unnecessary servicing intervals.
