Toxic and harmful gas detectors are used for long-term continuous monitoring of gas concentrations in the air and are installed in locations prone to gas leaks. They can be connected to corresponding gas alarm controllers to form a complete gas monitoring system.

This detector is designed in accordance with national standards, featuring high stability, low power consumption, and strong anti-interference capabilities. It is particularly suitable for flammable and explosive environments with harsh working conditions where personnel cannot easily approach. It is an ideal monitoring instrument for ensuring the safety of property and personnel.
