Calibration for Every Major Leak Standard

Calibration Compatibility Index

Spectro Physics calibrates leak standards from all major manufacturers. This page lists representative model families we support. It is not exhaustive — if your leak isn’t shown here, we can still calibrate it.

TL7 Internal Leaks

These are internal calibrated leaks installed inside helium leak detectors. They appear under various OEM part numbers depending on the manufacturer.

Representative Models

  • TL7

OEM Variants
