your best partner for vacuum


Integrated high quality components enable first-class performance for absolute measurement accuracy at outstanding speed. The simple navigation and robust construction make the EV-LX218 leak detector the ideal choice for companies in a wide range of industries. The helium leak detector has a start-up time of less than three minutes and offers a fast leak test and reaction time. A further advantage: With its vacuum mode and sniffing option, it is perfectly suited for efficient leak localization and leak size determination.

Competitive price thanks to standard components and direct distribution channels

Highest degree of availability and reliability, even after long periods of use, with proven vacuum technology components such as mass spectrometers, pumps and valves

Very short measuring times due to high pumping speed

Detection of the smallest leaks, even in environments contaminated by helium, with an intelligent stainless steel vacuum system

The highest quality in your production or service application guaranteed by high-precision measuring technology

Easy operation and installation, with no training required

Robust and versatile, it can be used even in the harshest production environments


The device is a leak detector for detecting and measuring leaks in test objects. The device is suitable for leak detection using the vacuum method and the sniffer method.

  • When using the vacuum method the test object is evacuated and subjected to helium or forming gas from the outside. To do this it is necessary to establish a vacuum connection between the device and the test object.
  • When using the sniffer method an overpressure is established in the test object using helium or a forming gas. The test object is then inspected on the outside using a sniffer line.
