Helium Leak Testing is typically performed in house using a Varian 936-40 Helium Mass Spectrometer Leak Detector. By using a "Calibrated Leak Standard" the equipment can be tuned to a sensitivity of 1E -11 Torr std. cc/sec. He.
All testing is performed in house on systems built by us. For customers that require leak testing on pre-existing systems that are leak suspect, we request that the systems be sent to our premises for evaluation and repair. Torrovap provides leak test certificates to A.S.T.M. standards. Advance notice is requested for leak detector availability scheduling.
