Product Description
The Zefon DigiCal™ 30 Primary Flow Calibrator (230V) is a NIST-traceable airflow calibration instrument designed for accurate verification of area and high-flow air sampling pumps, including Zefon Escort ELF and LC models.
Using a frictionless flow cell and quartz-controlled timing system, DigiCal provides instantaneous digital volumetric readings without bubble tubes — streamlining calibration while delivering repeatable, audit-ready results.
With ±0.5% accuracy at any altitude and up to 100 hours of runtime per charge, this compact primary standard is ideal for international industrial hygiene programs and regulated environments.
