Helium Concentration Tester

The LHCT03D Helium Concentration Tester is designed to verify helium gas content in production parts such as airbag inflator assemblies. Used alongside a helium mass spectrometer, this system delivers fast, accurate concentration readings to support quality control and process verification. It includes a high-sensitivity LSP-HCT-5 sniffer probe and a touchscreen interface for user-friendly operation and calibration. Compatible with a wide range of leak detectors, the LHCT03D is ideal for production environments requiring reliable helium validation.

Features

  • Measures helium concentration from 1% to 100%
  • Fast response time—typically under 5 seconds
  • 4.3″ color touchscreen with intuitive microcontroller-based interface
  • Includes LSP-HCT-5 sniffer probe for atmospheric pressure sampling
  • Simple calibration process ensures repeatable results
  • USB port for data collection and software updates
  • Ethernet and RS232 ports for system communication and barcode input
  • Integrates with most helium mass spectrometer leak detectors, including LACO TITAN VERSA
  • Ideal for verifying helium charge levels in airbag inflator assemblies

Helium Concentration Tester

LHCT Probe Tip Assembly

The LHCT Probe Tip Assembly is a replacement tip for the sniffer probe used with LACO’s Helium Concentration Testers (LHCT03 and LHCT03-R). This 10-32 threaded barb fitting features an integrated 30-micron bronze filter and is designed to puncture the foil on airbag inflators for direct helium sampling. If the tip becomes clogged or damaged during use, this replacement assembly restores proper function and sampling accuracy.

Features

  • Replacement tip for LHCT sniffer probes
  • 10-32 threaded barb fitting with integrated 30-micron bronze filter
  • Designed to puncture foil seals on airbag inflators
  • Ensures accurate helium sampling during concentration tests
  • Replace when clogged or worn from repeated use
