Qualitative Gas Leak Detector

The MOEORW-WQL13qualitative gas leak detector is a portable, battery-powered leak inspection device integrated with a microcontroller featuring advanced digital signal processing. Equipped with a built-in mechanical suction pump at the sensing port, the unit generates stable air intake flow to realize real-time gas leakage sampling. It supports one-handed operation with ergonomic keypad layout, multi-level adjustable sensitivity, tri-color LED visual alarm and audible alert system. The device delivers instant response and rapid zero reset after detecting heavy leaks, designed for continuous on-site gas leak screening of SF6 gas.

Working Principle
The internal mechanical suction pump draws ambient gas through the sensor nozzle and flexible probe into the sensing unit. The microcontroller processes gas concentration signals via digital signal processing algorithms. Concentration data is converted into graded visual tri-color LED prompts and synchronized audible alarms. Operators can adjust detection sensitivity via dedicated keys; the system automatically resets baseline within 1 second after high-concentration gas detection to avoid signal lag. Built-in battery monitoring module detects remaining voltage and displays real-time power status via dedicated test function.
