2. Smoke testing (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Smoke_testing_(mechanical)

   In plumbing a smoke test forces non-toxic, artificially created smoke through waste and drain pipes under a slight pressure to find leaks. [4] Plumes of smoke form where there are defects. This test can be performed when the plumbing is brand new, but more often it is used to find sewer gas leaks that may plague a building or an area. [ 4 ]

3. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station. Optimal detection distance varies and is influenced by camera lens size, resolution, field of view, thermal detection range and sensitivity, leak size, and other factors.

4. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   The ultrasonic gas leak detector then produces an alarm when there is an ultrasonic deviation from the normal condition of background noise. Ultrasonic gas leak detectors cannot measure gas concentration, but the device is able to determine the leak rate of an escaping gas because the ultrasonic sound level depends on the gas pressure and size ...

5. Aspirating smoke detector - Wikipedia

   en.wikipedia.org/wiki/Aspirating_smoke_detector

   An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. [1] The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.

6. Smoke detector - Wikipedia

   Smoke detector mounted on a ceiling Knowing this sound could save your life - it means replace the battery. A smoke detector is a device that senses smoke, typically as an indicator of fire. Smoke detectors/Alarms are usually housed in plastic enclosures, typically shaped like a disk about 125 millimetres (5 in) in diameter and 25 millimetres ...

7. Tracer-gas leak testing - Wikipedia

   en.wikipedia.org/wiki/Tracer-gas_leak_testing

   A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.
