This instrument requires a Gas Source to operate. Visit Customize Your Calibrator to view and choose all available gas sources.


Approved intrinsically safe with CE mark certification.


ACD is proud to feature the CAL-101, our low-cost electrochemical gas instrument. Field replaceable gas sources provide a calibration standard for accurately testing Chlorine, Hydrogen Sulfide, Hydrogen and Hydrogen Cyanide sensors. This calibration method is approved under the ISO DIS 6145-11 standards. The instrument is also designed to meet intrinsic safety requirements.


The CAL-101is non-hazardous to ship and will not degrade over time. The sources are interchangeable and provides multiple gas and concentration options quickly, safely and easily. By simply inserting the appropriate source into the instrument, the user is ready to calibrate.


The CAL-101‘s compact size and lightweight provide for a safe and easy calibration even for the least accessible detection points. The two 'AA' batteries powering the instrument combined with an efficient design provide the user with a light-weight instrument weighing approximately 1 pound (0.45 kg).
