Gas leak detector GLD10

Gas Leak Detector GLD10 is a compact leak testing system, equipped with a dedicated electronic device for easy process controlling and monitoring.

The unit is prepared to work in automatic industrial leak detection systems. Allows leak detection at the lowest measurable levels. Thanks to the implementation of the advanced data transmission protocol and easy, user-friendly control interface, GLD10 allows complete integration with the latest production management systems based on the specification of industry 4.0.

  • Prepared for integration with industrial PLC systems for serial testing
  • High resolution
  • High reliability
  • Easy to connect
  • Suitable for automated processes


In the spectrometer of the leak detector, the ionized gas atom’s path is bent in a magnetic field, and geometry and control voltage are set for measurement of light gases like Helium 3, 4 AMU or Hydrogen 2 AMU. GLD10 requires a backing pump (available as an option).



Leak tests are performed, for example:

in the industrial vacuum processes:

  • furnaces: metal enhancement,
  • coating lines: glass coaters for optics,
  • food packaging,
  • process reactors: electronics manufacturing.

in the production of automotive parts:

  • economics: energy loss due to pressure drop (air conditioning),
  • ecologics: leaks of dangerous media (fuel),
  • safety: leaks of flammable gases or fluids (brake fluid).

in the production of consumer electronics with heat pumps:

  • economics: energy loss due to pressure,
  • ecologics: leaks of dangerous media,
  • safety: leaks of flammable gases or fluids.
