Helium Leak Detectors | Mass Spectrometer Leak Detector ...

At the origin of the helium leak detection method was the ”Manhattan Project” and the unprecedented leak-tightness requirements needed by the uranium enrichment plants. The required sensitivity needed for the leak checking led to the choice of a mass spectrometer designed by Dr. Nier tuned on the helium mass. Because of its industrial use, the material choice (originally glass ...

The leak detector for mandatory testing | Testo Ltd

The gas leak detector has an integrated pump for this purpose. It quickly detects the gases present in the ambient air, such as methane and propane, and establishes the location of the gas leak. The gas concentration is shown in a simplified bar format on the display of the absolute pressure measuring instrument. If the limit values are exceeded, the instrument generates an alarm.

Gas Detector Installation | Gas Detector Placement

· However CO2 is a toxic gas under UK COSHH and US OSHA regulations. This means you need to have systems in place to monitor for any Co2 leaks. Importantly those visiting commercial refrigeration sites need to protect themselves from the toxic effects of CO2. Our article addresses this issue and why you need a portable CO2 detector and our iGAS CO2 portable monitor.
