CCDI not only manufactures internal sonic nozzles, we also fabricate external sonic nozzles (ranging from .015" to 2.000") for use in the calibration of airflow stands. We can manufacture smaller or larger sizes to accomodate specific customer requirements.

Our airflow stands use premium grade sonic nozzles, also known as critical venturi nozzles, to measure airflow through any device that you may need to test. CCDI is now an accredited NVLAP-600240-0 Calibration Laboratory ISO/IEC 17025:2017.
