tetraCal® Air Flow Calibrator

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.

Calibration of particulate samplers and industrial hygiene
Total flow range of 1.2 to 30 LPM
Ultra-model provides a flow range of 1 to 60 LPM
Continuous uninterrupted output display of all parameters
Higher flow Ultra Model allows for calibration of European standard PM samplers
