Our new and improved Helium Sniffer Probe features an all new, capillary tube sniffer tip for more accurate flow. The LSP-01HS-NW25-33 is an ideal accessory designed to convert your Leybold or other non-Alcatel helium mass spectrometer leak detector to sniffer mode without the expense of a new leak detector. The helium sniffer probe fits onto the leak detector’s vacuum port and converts the vacuum port to a sniffer port. Probe is designed for gross mode or inlet pressures above 0.1 Torr or 100 millitorr. Connects to vacuum test port of leak detector. Test port size is NW 25 sized flange. Includes 33 feet of hose and is packaged in a durable storage and carrying case.

Fits any Oerlikon/Leybold Phoenix L300i, L300i DRY, L300i Modul, L320i Fab, L340i, L500i leak detector. Also compatible with leak detectors using NW fittings at inlet port
