Product Introduction
The PQ125B Leak detector is a new generation of intelligent detection equipment independently developed by our institute, designed specifically for pressure pipeline leak detection scenarios in municipal, fire, and thermal applications. The equipped sensor is configured as the acoustic resonance sensor RC-S3, which is suitable for external pipeline detection needs.
This instrument utilizes its core technology of precise sound signal acquisition and intelligent analysis algorithms to achieve centimeter level leak point positioning accuracy. It effectively solves the industry challenge of detecting outdoor pressure pipeline leaks and provides efficient and intelligent technical solutions for municipal maintenance and fire safety pipeline management.
