MesaLabs Direct Reading Calibrator HiVol Cal

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
