Air flow calibrator tetraCal®

pressurelaboratory

The BGI tetraCal® is a simple-to-use standard for volumetric airflow, barometric pressure, and ambient temperature. The tetraCal is a venturi based system with built-in compensation for changes in ambient temperature and pressure. All tetraCal systems are built and tested at Mesa which is a NIST traceable Calibration Laboratory.
