• All Types, All Models

• Point to Point Calibration

• NIST Traceable Accuracy

• Any Gas Reference

• Full Vacuum Range

All vacuum gauge calibrations are performed in accordance with HLT-QAM, Rev. B, Jan. 17, 2005.

Our Quality System is routinely audited and approved to meet customer requirements which conform to, MIL-STD-45662A, ISO 9000, ISO-10012, ISO/IEC 17025, and ANSI Z540 programs.

HLT calibration masters are tested by NIST, therefore directly traceable to NIST in order to maintain an unbroken chain of competent calibrations.

HLT’s calibration laboratory is geared for accuracy and quick turnaround. Equipped with the latest technology and highly trained staff , we service and calibrate all types and models of vacuum gauges. Specialty gas calibrations and expedited schedules are available upon request.
