ACD CAL-2000


NIST traceable certification.
Interchangeable calibration gases.
Adjustable PPM and flow rate.
Unlimited shelf life.
Non-hazardous shipping.
Intrinsically safe (CSA Certified).



Field replaceable electrochemical generating Sources provide a standard for accurately calibrating both fixed and portable detection systems from any manufacturer.
The CAL 2000 is microprocessor controlled and has an LCD display allowing field adjustable concentration and flow rate. The generating Sources are interchangeable and field replaceable. Best of all, the CAL 2000 generating Source provides up to 50 times as much calibration gas as a disposable cylinder at approximately the cost of just two cylinders.


The CAL 2000 gas instrument has a built-in mass flow sensor that automatically compensates for altitude and temperature.
