Helium Mass Spectrometers are precision instruments requiring periodic calibration. They are sensitive to system outgassing and a number of background effects. Using a calibrated leak standard allows these to be measured and subtracted from the overall reading. LACO provides leak standards for a number of major He Mass Spectrometer brands, including LACO's TITATEST Helium Leak Detector.

LACO provides helium calibrated leaks for many OEM suppliers. We can a either re-calibrate your old leak or provide a new one.
