Description

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 both a NIST traceable Calibration Laboratory and an ISO 17025 facility.

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.
