SF6 GasCheck 6000

General Details

The ideal low cost SF6 leak detector

The SF6 GasCheck 6000 leak detector is a great device for mobile SF6 leak detection. In practical use, it has a detection threshold of 1×10-6 mbar l/s, which makes it perfectly suitable for simple leak detection applications on SF6 switchgear.

The easy to use, processor controlled instrument features both an audible alarm and an LED bar graph display, letting you know if a small, medium or big leak has been detected.

The leak detector automatically compensates all ambient influences like temperature changes or movement of air in the room. Intelligent control sets up the instrument appropriately for the ambient situation.

The ‘Auto Shift’ function

The exclusive ‘Auto Shift’ function compensates for any SF6 concentration that may be present at the measuring site, e.g. caused by previously escaped leakage gas.

SF6 GasCheck 6000 automatically detects the highest present gas concentrations, and selects the corresponding measuring range. It then uses the present gas concentration as its zero line, and begins to look for even higher gas concentrations, which by all means occur when a leak is approached. This will again be indicated audibly and visually. It is thus possible to determine leaks even in an already seriously contaminated area.

The assessment of large leaks is often useful to get an idea of a component’s leak tightness, before much more sensitive instruments like SF6 LeakCheck P1:p must be used.


Low cost, effective detection of SF6 leaks. The SF6 GasCheck 6000 is a low cost, portable detector for the fast detection of SF6 leaks.
