Mesa Labs Definer 220 Differential Pressure Recorders This unit is the workhorseThe 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
