product description

Gas introduction:

Methane, chemical formula CH4, is the simplest hydrocarbon (tīng, hydrocarbon), the molecule is a regular tetrahedral space configuration, the C-H bond energy is 413 kJ / mol, and the H-C-H bond angle is 109 ° 28 ′. The structural formula of methane only indicates the connection of atoms in the molecule, and it cannot truly represent the relative position of each atom in space. Methane is a colorless, flammable and non-toxic gas under standard conditions. Methane is widely distributed in nature and is one of the main components of natural gas, biogas, pit gas, and gas. It can be used as fuel and raw materials for the production of hydrogen, carbon monoxide, carbon black, acetylene, hydrocyanic acid and formaldehyde.

Methane gas probe applications:

Petroleum and petrochemical, chemical industry, smelting plant, steel plant, mining plant, thermal power plant, pharmaceutical production workshop, environmental monitoring, fire alarm, sewage treatment, gas station monitoring, security inspection, inspection and quarantine, etc. It is mainly used to monitor indoor and outdoor methane gas leaks. When there is a methane gas leak, the detector will detect the leakage information and display the concentration of the leaked methane gas in real time, and timely transmit the relevant data to the controller. When a certain concentration is reached, The controller will prompt the user that a gas leak has been detected, and the associated equipment and related personnel take relevant measures, which are important instruments to ensure the safety of the environment, production, and life and property.
