ULVAC HELIOT ZERO Helium Leak Detector
The HELIOT ZERO is a compact, portable helium mass spectrometer leak detector designed for sniffer method applications. It does not include an internal fore vacuum pump — the HELIOT ZERO is connected to an existing roughing pump or used with specific ZERO accessories. Two models are available for different markets.
| Model | Part number | Region | Notes |
|---|---|---|---|
| HELIOT ZERO-J | 210006406300 | Japan | Japan market. Power supply cable and test port sold separately. |
| HELIOT ZERO-F | 210006406400 | Overseas | Overseas (non-Japan) market. Power supply cable and test port sold separately. |
The HELIOT ZERO does not include a backing pump. A fore vacuum pump is required for operation. Enquire about compatible fore pump options when ordering.
