Calibration Services

Helium Leak Testing, Inc. calibration capabilities include all models and ranges of leak standards. We offer competitive pricing and turn-around times. Special calibrations include specific leak rates, pressure differentials and unique gases. Our vast inventory of hardware can adapt to any port connection.

Specialty gas calibrations and expedited schedules are available upon request.

All vacuum gauge calibrations are performed in accordance with HLT-QAM, Rev. H. Helium Leak Testing calibration masters are tested by NIST, therefore directly traceable to NIST in order to maintain an unbroken chain of competent calibrations.
