The Cal 2000 from ACD provides unmatched versatility and accuracy in calibration gases, including corrosive types that are otherwise unstable when stored in cylinders. Field replaceable electro-chemical generating cells provide an NIST traceable calibration standard for accurately testing chlorine, chlorine dioxide, hydrogen, hydrogen cyanide, and hydrogen sulfide gas sensors.
If you use quantities of any of these gases, the economics and convenience being offered is compelling.
Value Proposition
With a standard 58 liter calibration gas cylinder and a 1 liter-per-minute regulator, you get almost 60 minutes of flow. For most of these gases, that will cost you about $200, and have a shelf life in the 6-12 month range. The CAL 2000 instrument costs $1600, and a 50 hour cell costs $600. Taken together, this is the equivalent of $44 per cylinder (even less on replacement cells!), with no shelf life. And not only that, think of the shipping. HazMat fees for compressed gas cylinders via UPS or FedEx add up quickly. The CAL 2000 and cells may be shipped air freight with no HazMat fee.
The Cal 2000 is microprocessor controlled and has an LCD display allowing field adjustment of the ppm concentration and flow rate. The generating cells are interchangeable and field replaceable. Best of all, the Cal 2000 provides up to 50 times as much calibration gas as a disposable cylinder, at approximately the same cost. The electrochemical generating cells do not degrade over time.
The Cal 2000 gas generator has a built-in mass flow sensor that automatically compensates for altitude and temperature. The mass flow sensor, combined with the instruments internal pump, provide extreme flexibility for calibrating both diffusion and sample draw detection systems.
