Journal 3

Today I will share some knowledge in journal 3, about the history of gas leak detector, who was use the first gas detector  and function, and the world first gas detector company?

History of gas leak detector.

Gas leak detection methods became a concern after the effects of harmful gasses on human health were discovered. Before modern electronics sensors, aerly detection methods relied on less precise detectors. Through the 19th and early 20th centuries, coal miners would bring canaries down to the tunnels with them as an early detection system against life-threatening gasses such as carbon dioxide, carbon monoxide, and methane. 

Who was use the first gas detector and function?

The first gas detector in the industrial age was The flame Safety Lamp (or Davey's Lamp) was invented by Sir Humphry Davey (of England) in 1815 to detect the presence of Methane (Firedamp) in underground coal mines. The Flame Safety Lamp consisted of an oil flame adjusted to specific height in fresh air. To prevent ignition with the lamps flames height varied depending on the sleeve with a mesh flame arrestor. The flames height varied depending on the presence of Methane (higher) or the lack of Oxygen (lower). To this day, in certain parts of the world Flame Safety Lamps are still in service. 

The worlds first gas detector company?

The worlds first gas detection company is Johnson-Williams Instruments (or J-W Instruments) was formed in 1928 in Palo Alto, CA by Dr. Oliver  Johnson and Phil Williams. J-W Instruments is organized as the first electronics company in Silicon Valley over the next 40 years J-W Instruments pioneered many "firsts" in the moderm age of gas detection, including making instruments smaller and more portable, development of a portable Oxygen detector as well as the first combination instrument that could detect both combustible gases/vapors as well as Oxygen.
