Tips: The necessity of a hydrogen gas detector.

Hydrogen (H2) has the physical properties of colorless and odorless, and the flame is transparent when burned. Therefore, the presence of hydrogen in the environment is not easy to detect by the senses. Generally, Ethyl mercaptan is added to the hydrogen gas so that it can be detected by the senses and make the flame appear color. However, when judging whether hydrogen has leaked, we cannot judge by ignition. Because using an open flame to check hydrogen is tantamount to igniting a time bomb, which is very dangerous. Therefore, it is necessary to use a hydrogen gas detector to monitor the environment where H2 may leak on-line.

Hydrogen is mainly stored in liquid form. The liquid H2 overflows and evaporates suddenly in a large area, which can also cause hypoxia in the environment, and may form an explosive mixture with the air, causing a combustion and explosion accident.

ATO hydrogen gas detector is an instrument that can continuously detect the concentration of H2 in the environment. It uses the natural diffusion method to detect the H2 concentration, with an electrochemical sensor. The use of hydrogen detectors can reduce the occurrence of H2 explosion accidents.
