Features: This detector can simultaneously detect combustible gas, oxygen, carbon monoxide, and hydrogens sulfide, meeting the safety monitoring needs of multiple environments. Adopting advanced sensing technology to ensures rapid response and accurate measurement of gas concentration changes, enhancing safety. Equipped with digital display screens, real-time display of various gas concentrations helps users understand environmental conditions in a timely manner. The built-in sound and light alarm systems will sound an alarm when the gas concentration exceeds the set value, reminding the user to take necessary measures. Lightweight and easy to grip design, convenient for use in various work environments such as industrial site, laboratories, and other enclosed spaces. Specifications: Component: ABS.
