Helium Leak Detector UL1000
Speed, Sensitivity and Reliability for Demanding Leak Detection Applications. The INFICON UL1000 Mobile Helium Leak Detector is designed to meet the most demanding industrial leak detection applications. Providing fast, accurate and repeatable test results, testing flexibility, and high sensitivity in a low maintenance design, the UL1000 is ready to tackle the toughest leak detection jobs industry can offer. The UL1000 is optimized to provide quick, accurate results in any application from the leak checking of large vessels and systems to high-cycle, repetitive component testing – 24 hours / 7 days a week – in the toughest industrial environments.

With the addition of the TC1000 Test Chamber accessory, the UL1000 Helium Leak Detector provides easy, fast and accurate testing of hermetically sealed parts like IC packages, quartz crystals and laser diodes

(according to MIL-STD 883, Method 1014).


  • Wide measurement range over 15 decades
  • Short pumpdown and response time
  • Mobile all-metal housing for added convenience with uncompromised maneuverability
  • I-CAL (Intelligent Calculation Algorithm for Leak rates)to ensure fastest response time to leaks in all measurement ranges
  • Zero function with automatic integration time alignment for fast and reliable leak test results
  • Intelligent vacuum design with rugged roughing pump and multiple inlet turbomolecular pump that provides high helium pumping speed with high compression
  • Rotatable display and user interface allows simple and easy control and interaction with the unit
  • Self-protection features to protect the UL1000 from helium and particle contamination
  • Auto purge cycle to ensure clean-up and readiness for leak test
  • Software updates via email easily possible
  • Rugged mass spectrometer system with two filament ion source (with 3-year warranty) ensures long running time and low maintenance costs
  • Built-in test leak for internal calibration to ensure accurate test results
  • Built-in software menu “Auto Leak Test” function to perform automatic testing of hermetically sealed components (optional TC1000 Test Chamber)

Typical Applications

  • Leak testing and quality control of all types of components, including:
    • automotive components
    • refrigeration and air conditioning components and sub-assemblies
    • hermetically sealed electronic devices
    • heat exchangers
