Helium Calibrators

Using the Calibrator

To calibrate a Helium Sniffer Leak Detector (or detector set to measure other gases such as SF6), the operator places the tip of the sniffer probe briefly into the tapered recess at the point source of gas flow of the FSLC. The leak-rate reading of the Detector is then adjusted to the Leak Rate of the Calibrator, as provided by VTI on the Calibration Tag. A second reading is obtained in the same way to assure the calibration of the detector.

You should compare the FSLC periodically to another Calibrated Leak if available, and return it to VTI for recalibration in accordance with your Quality Assurance/ISO schedule requirements.

Reliable Calibration of the Sniffer Leak Detector is fundamental to effective operation.

The "point-source" design for the gas flow assures that excessive calibration gas will not accumulate in "dead spaces" to cause erroneous high readings during detector calibration, which can later result in "passing" bad product.
