The Definer 220 allows users to verify gas flow rates in the field or the lab to an accuracy of ±1% percent of reading, including temperature and pressure compensation. Unlike thermal mass flow meters, Definer 220"'s positive displacement technology immediately indicates the 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.

The Definer 220 represents the next generation of our Proven DryCal ® Technology, which was developed specifically for critical industrial and environmental applications. It provides the accuracy, customization and durability needed in today's exacting, fast-paced workplace.
