Jan 01, 2001 · gas detectors (halogen, helium and hydrogen). The first three techniques, due to their characteristics and sensitivity, can be used only for gross leak detection (300 g/y (10.5 oz) or more refrigerant leakages). Tracer gas leak testing methods are much more precise than the previous group but, in many cases, their theoretical
