This system is used for locating water leaks and refrigerant gas leaks.
The leaking system is filled with the gas and the escaping gas is located with a highly sensitive computer.
The mix of gas is 95% Nitrogen and 5% hydrogen. Hydrogen will pass through any material; concrete, tiles, ground, due to it being the smallest molecule.
This environmentally friendly gas mixture is neither combustible, toxic nor corrosive.
Because it reacts so accurately and quickly, the system is ideally for precisely locating even the smallest of leaks
