Product Description
Primary Flow Calibrator for Area Sampling Pumps – 110V Version
The Zefon DigiCal™ 30 Primary Flow Calibrator (110V) is a precision, NIST-traceable calibration instrument designed for verifying airflow in area and high-flow air sampling pumps, including Zefon Escort ELF and LC models.
Its frictionless flow cell and quartz-controlled timing system replace bubble tubes with instant digital volumetric readings, speeding setup while delivering repeatable, audit-ready performance.
With ±0.5% accuracy at any altitude and up to 100 hours of operation per charge, this compact primary standard supports regulated industrial hygiene programs across U.S. facilities.
