Product Description
Primary Flow Calibrator for Personal & Environmental Sampling Pumps
The Zefon DigiCal™ 5 Primary Flow Calibrator is a precision, NIST-traceable calibration instrument engineered for airflow verification of personal and area air sampling pumps, including Zefon Escort ELF and LC models.
Using a frictionless flow cell and quartz-controlled timing system, DigiCal delivers instantaneous digital flow readings without bubble tubes, making calibration faster, cleaner, and more repeatable in the field or lab.
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 and defensible sampling results.
