Overview
The portable gas detector enables mobile detection of oxygen, combustible gases, toxic and hazardous gases in the atmosphere. It can be flexibly configured with up to 6 different types of sensors as needed. Its core detection technologies encompass electrochemical, infrared, catalytic combustion, thermal conductivity, PID (photoionization detection), and other principles. The device integrates imported sensors with high-speed, high-precision processing circuits, offering advantages such as excellent signal stability, high detection accuracy, and superior data repeatability. It is widely applicable across industries including petroleum and petrochemicals, metallurgy, environmental monitoring, gas safety, fire rescue, municipal engineering, chemical production, marine operations, power systems, process control, wastewater treatment, and emergency response monitoring.
