The Cal 2000 Gas Generator features field replaceable, electrochemical generating cells provide a calibration standard for accurately testing chlorine, chlorine dioxide, hydrogen, hydrogen cyanide and hydrogen sulfide gas sensors.

The Cal 2000 is microprocessor controlled and has an LCD display allowing field adjustable ppm 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.
