The parameters are just for your reference, don’t just read the words and make yourself angry.
Only by tasting sorrow and swallowing bitterness can a fragile heart learn to be strong. As long as you have unchanging dreams, there will be hope ahead. Passing through the years, walking day and night, this road has been bumpy and bumpy, leaving deep and shallow footsteps. Looking back at dusk, this bumpy road is a picture of life. Spring goes and autumn comes, and it will never fade.
A brief description of the methane power-off instrument for coal mines
The methane power-off instrument for coal mines consists of three parts: a main engine of the methane power-off instrument for coal mines, a dual-channel methane sensor and an audible and visual alarm. composition. It is suitable for environments where flammable, explosive and combustible gas mixtures exist. When methane exceeds the limit, the power supply of the controlled equipment will be automatically cut off.
Features
