GAS-CAL© Portable Gas Flow Calibrator
Combined Technology for Precision Gas Flow Calibration. The GAS-CAL© instrument has a built-in pressure standard with a PC-based interface with Venturi Nozzles and the IGFS. The GAS-CAL© gas flow calibrator uses multiple technologies for precision gas flow testing, calibration, and analysis in the field, on the shop floor, or in the lab.
Options: Stand Alone Standards or Complete GAS-CAL© System built to meet your specific requirements.
