Portable 4-in-1 gas detector alarm
Portable 4-in-1 gas detector alarm
- Multi-gas detection capability: It can detect four different gas concentrations at the same time, such as oxygen (O₂), combustible gas (LEL), carbon monoxide (CO) and hydrogen sulfide (H₂S), etc., to meet diverse monitoring needs.
- High-precision sensor: Equipped with high-precision sensors, it can accurately measure gas concentrations to ensure the accuracy and reliability of data. These sensors usually have fast response time and long-term stability.
- Easy to operate and maintain: The operation interface is simple and intuitive, and it is easy to use. At the same time, maintenance is relatively simple, usually only requiring regular replacement of sensors or calibration.
Product Overview:
This portable gas detector uses advanced large-scale integrated circuit technology to detect gas by natural diffusion. The sensitive element uses high-quality gas sensors with excellent sensitivity and excellent repeatability. It is easy to use and maintain, and greatly meets the requirements of industrial site safety monitoring for equipment reliability. The shell is made of high-strength engineering plastics, which is strong and durable, feels good, and is waterproof, dustproof, and explosion-proof.
It can be widely used in various industries such as petroleum, chemical industry, environmental protection, metallurgy, refining, gas transmission and distribution, biochemical medicine, and agriculture.
Application:
Petroleum, chemical, metallurgy, steel and other industries: In these industries, the portable 4-in-1 gas detection alarm can be used to detect combustible gases, toxic gases (such as carbon monoxide, hydrogen sulfide, etc.) and oxygen concentration in the production environment to ensure production safety.
Mines: In relatively restricted and enclosed spaces such as mines, pits, and tunnels, detect the concentrations of gases such as oxygen, carbon monoxide, carbon dioxide, and hydrogen sulfide to prevent poisoning and suffocation accidents.
Construction sites: Detect the concentration of harmful gases in the construction environment, such as formaldehyde, ammonia, etc., to ensure the health and safety of construction workers and prevent gas leakage accidents.
