[Professional Noise Reduction Ear Protection] Use practical noise reduction handle buttons and independent noise reduction switches to reduce environmental sound interference. Equipped with over-ear earmuffs, it can effectively protect hearing during mobile inspection operations in complex working environments. [High-definition digital data display] Adopts a high-definition LCD screen to intuitively display real-time detection values. The larger the value, the closer it is to the pipeline leakage point, helping workers to quickly and accurately locate hidden leakage locations. [Adjustable multi-frequency detection mode] Equipped with 4 optional frequency gears and built-in high-sensitivity sensors, parameters can be flexibly adjusted according to on-site pipeline conditions, effectively improving the overall detection accuracy [Indoor Detection Sensor] Supports the selection of indoor special sensors based on the actual indoor space size to achieve targeted detection and improve the adaptability of detection equipment to different indoor installation environments. [Various application scenarios] Suitable for daily household water supply pipeline inspection, fire protection system inspection, floor heating pipe leakage inspection, building infrastructure inspection and municipal engineering pipeline maintenance work, Manufacturer: Fcttcd
