As we all know, the four-in-one gas detector can simultaneously detect oxygen, combustible gas, hydrogen sulfide, carbon monoxide and other gases. The four-in-one gas detector, also known as the composite gas detector, has changed the disadvantage that it can only detect 1 kinds of gas, and meets the needs of petrochemical, paint, electric power, metallurgy, environmental protection, papermaking and other industrial industries. Let's listen to the technicians of Yiyuntian to share their little understanding of the four-in-one gas detector!

1. What is the dark display and low sound of the four-in-one gas detector?

Generally speaking, if the four-in-one gas detector needs to be fully charged before use, the screen display and sound will be normal when opening the inspection.

if necessary, the four-in-one gas detector needs to be calibrated and maintained in time after use in particularly harsh environments.

2. How is the four-in-one gas detector connected to the alarm device?

When the concentration of some detected gases is too high, especially the concentration of combustible gases and toxic and harmful gases, it is necessary to give an alarm to the user to prevent accidents.

The ordinary four-in-one gas detector has the function of setting the gas concentration alarm value. When the gas concentration is too high, the buzzer of the four-in-one gas detector will sound an alarm. The four-in-one gas detector can also communicate with some peripheral devices to connect and transmit alarm values.
