Primary Gas Flow Calibrators
Ideal calibrator for critical industrial and environmental sampling applications. 
Invaluable tool for process control engineers and workers who need to perform a quick flow verification check of flow meters (such as mass flow controllers) on the manufacturing floor or in the field.

The Definer 220 allows users to verify gas flow rates, in the field or in the lab. It is backed by Proven Bios DryCal® Technology for fast, ±0.75% of reading volumetric calibrations and ±1% of reading standardized calibrations. Unlike thermal mass flow meters, the Definer 220′s positive displacement technology provides immediate indication of actual volumetric gas flow rate – accurately and independently of gas type. Integrated temperature and pressure sensors in the flow stream allow users to automatically standardize volumetric flow readings to standard conditions, for traceable verifications of mass flow devices. It provides the accuracy, customization and durability needed in today’s exacting, fast-paced workplace.

For use with non-corrosive, non-condensing, non-combustible gases, less than 70% humidity.
