HiVol Cal Direct Reading Calibrator

The BGI High-Volume Calibrator (HiVol Cal) is a simple-to-use, NIST Traceable Standard for volumetric air flow, barometric pressure, and ambient temperature.

The HiVol Cal is a venturi based system with built-in compensation for changes in ambient temperature and pressure. All HiVol Cal systems are built and tested at Mesa which is a NIST traceable Calibration Laboratory.

Simply connect, read and adjust the flow controller of the HiVol to the BGI HiVol Cal. Adapters are available for easy calibration of 2” radiological filter holders and 8×10” filter holders. The HiVol Cal is a preferable alternative to standard orifice calibration.
Total flow range of 7 – 54 CFM
NIST-traceable accuracy ≤ 1% of flow reading
Continuous uninterrupted output display of all parameters
Adapters available for 2” and 8×10” filter holders
