Digital Flowmeter 220L PTC
The 220L Digital Flowmeter with flow rates from 5 mL/min to 500 mL/min, allows users to verify gas flow rates, in the field or in the lab, to an accuracy of ±1% percent for readings standardized for temperature and pressure and ±0.75% in volumetric flow.
Unlike thermal mass flow meters, the 220L 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.
A versatile, push-button flow meter, the 220L enables the user to accurately calibrate a variety of instruments while maintaining an ISO 17025-traceable audit trail.
