  • Detecting Sulfur Dioxide Leak | HVAC Troubleshooting

    To detect sulfur dioxide leaks, an ammonia swab may be used. The swab is made by soaking a sponge or cloth tied onto a stick or piece of wire in aqua ammonia. Household ammonia may also be used. A dense white smoke forms when the ammonia comes in contact with the sulfur dioxide.

  • Fundamentals of leak detection - Leybold Online Shop

    The leak rate of a vessel indicates the amount of gas flow which escapes through the walls of the vessel. It must be noted, however, that the leak rate for a leak depends on the type of gas. If the gas temperature T and the molar mass M of a gas G is known, the gas mass flow can be calculated from the leak rate
