2. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   A typical calibration schedule for a portable gas detector is a daily "bump test" accompanied by a monthly calibration. [17] Almost every portable gas detector requires a specific calibration gas In the US, the Occupational Safety and Health Administration (OSHA) may set minimum standards for periodic recalibration.

3. Photoionization detector - Wikipedia

   en.wikipedia.org/wiki/Photoionization_detector

   The photoionization detector is an efficient and inexpensive detector for many gas and vapor analytes. PIDs produce instantaneous readings, operate continuously, and are commonly used as detectors for gas chromatography or as hand-held portable instruments. Hand-held, battery-operated versions are widely used in military, industrial, and ...

4. Hydrogen sensor - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_sensor

   A hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen sensors and are used to locate hydrogen leaks. They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments. [1]

5. 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.

6. Ionization chamber - Wikipedia

   en.wikipedia.org/wiki/Ionization_chamber

   Plot of ion current against voltage for a conceptual wire cylinder gaseous radiation detector. Ion chambers use the lowest voltage plateau. A gas ionization chamber measures the charge from the number of ion pairs created within a gas caused by incident radiation. It consists of a gas-filled chamber with two electrodes; known as anode and ...
