UL260
Proven performance. Simply delivered.
Everything You Need to Find a Leak. Nothing You Don't.
Leak testing should not require an oversized budget or a specialist team. Low-cost instruments often raise doubts about measurement quality, while high-end systems exceed both budget and requirements.
The UL260 closes that gap. It is a helium leak detector for vacuum leak testing in industrial applications, built on a platform with more than two decades of field experience. Application know-how, worldwide service and an upgrade path that stays open come with it.
We back the platform with an extended warranty: 3 years on the ion source and 2 years on the complete instrument. Your operating costs stay predictable from the first day of use.
Advantages
- Proven INFICON technology: more than 20 years of field-tested design
- Lower investment and total cost of ownership: long-proven core parts, no surplus functions
- Predictable costs
- Simple installation and operation: ready to measure without specialist training
- Measurement confidence without in-house expertise: our application engineers are on call
- Worldwide service: service centers and trained technicians in every region
- Open upgrade path: Integration with your process control system using the LD or ASCII Protocol

Every Feature Earns Its Place
Every component serves the measurement. The result is a detector that starts quickly, runs simply and fits the bench it stands on.
- Proven measuring cell: 180° sector field mass spectrometer with a two-filament iridium ion source. The counter-flow design keeps results repeatable across the full range. The ion source is covered by a 4-year warranty.
- Fast readiness: about 2 minutes to fore-vacuum and 3 minutes to ion source readiness, so the instrument is ready at the start of the shift.
- Helium pumping speed of 2.5 l/s: clears tracer gas quickly between parts, sized for components, sub-assemblies and small series.
- Inlet pressure up to 25 mbar: pre-evacuation can end earlier, which shortens the pump-down phase of every test cycle.
- Compact 42 kg benchtop format: 556 x 304 x 460 mm. Fits a standard workbench and moves between stations without a lifting aid.
- Direct-access operation: start, stop and zero via dedicated keys. Trigger levels and calibration stay set between shifts.
Configuration and Accessories
- Sniffer line: extends the instrument from vacuum testing to local leak location on the part
- RC1000 remote control: operation and acoustic leak indication directly at the test object
- Qualified external fore-vacuum pumps: oil-sealed or dry pumps, qualified and supplied by INFICON
- Partial flow system: adapts the instrument to larger test volumes
- Instrument cart: turns the benchtop unit into a mobile leak test station
- Easy-Start video call: a complimentary guided first start-up, included with the instrument
