Versatile leak detection for a multitude of applications

Using trace gas is a tried and tested method of leak locating. It can be used in water and gas distribution networks, pipes in buildings, heating systems, pressurized communication cables, gas-filled high-voltage power lines and garbage areas insulated with double membrane layers. Also, such as pipe, pump, engine block and weather plate.
It can also be used to test for leaks in industrial products.

includes. Hydrogen is the lightest that can be found in the leak zone by the high-sensitivity VARIOTEC 8 trace gas sensor.
gas and pen. Two measuring ranges in the ppm range and vol% for the above ground detection. Location of underground cables in the range of VARIOTEC®8-Trace gas ensures standardization in this equipment group. Sensor and firmware are best used for locating underground cables.

The low hydrogen content (only 5%) means that this method is completely safe: this gas is non-flammable according to ISO 10156, thanks to the use of nitrogen as the carrier gas. Besides being non-corrosive, it is also non-toxic and thus allowed to be used in drinking water networks. Tracing gas is inexpensive and easy to obtain from technical gas or gas source dealers. It penetrates all layers such as asphalt, concrete and other covering layers and is neutral. The trace gas always seeks the shortest path from the leak area to the surface.

A wide range of accessories is available for testing many applications:

Carpet probe for testing fixed surfaces Bell probe for testing on the surface or large areas Locating probes for pinpointing the exact point of damage in underground cables Hand-held probes for testing in indoor installations
