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
