  2. Socket wrench - Wikipedia

    en.wikipedia.org/wiki/Socket_wrench

    A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt. [2] The most prevalent form is the ratcheting socket wrench, often informally called a ratchet.

  3. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    The type of oxygen sensor used in most underwater diving applications is the electro-galvanic oxygen sensor, a type of fuel cell, which is sometimes called an oxygen analyser or ppO 2 meter. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and trimix. [9]

  4. Electro-galvanic oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Electro-galvanic_oxygen_sensor

    This test does not only validate the cell. If the sensor does not display the expected value, it is possible that the oxygen sensor, the pressure sensor (depth), or the gas mixture F O 2, or any combination of these may be faulty. As all three of these possible faults could be life-threatening, the test is quite powerful.

    Service / Mode $05 displays the oxygen sensor monitor screen and the test results gathered about the oxygen sensor. There are ten numbers available for diagnostics: $01 Rich-to-Lean O2 sensor threshold voltage; $02 Lean-to-Rich O2 sensor threshold voltage; $03 Low sensor voltage threshold for switch time measurement

  6. Oxygen saturation - Wikipedia

    en.wikipedia.org/wiki/Oxygen_saturation

    It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. [1] The standard unit of oxygen saturation is percent (%). Oxygen saturation can be measured regionally and noninvasively. Arterial oxygen saturation (SaO 2) is commonly measured using pulse oximetry.

  9. Electrochemical gas sensor - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_gas_sensor

    The gas diffuses into the sensor, through the back of the porous membrane to the working electrode, where it is oxidized or reduced. This electrochemical reaction results in an electric current that passes through the external circuit. In addition to measuring, amplifying, and performing other signal processing functions, the external circuit ...
