Feature 1PRODUCT FUNCTION: Water pipe leakage monitor is F 999R accuracy instrument, sound amplification 25000 times, probe sensitivity 60db, with automatic noise reduction function, HD listening device. 2APPLICABLE SCENARIO: Water leak detection kit can be used for pipeline side leakage, floor heating, geophysical water detection, suitable for various pipeline materials, floors, wall, etc. 3FINE WORKMANSHIP: All metal body, finely crafted, for accuracy professional instruments and equipment. Superior performance, clear sound quality, strong sensitivity, and accuracy components. Functional jack with recording functions. 44 GEAR ADJUSTMENT: 3rd gear (100Hz to 700Hz) 2nd gear (700Hz to 900Hz) 1st gear (900Hz to 1100Hz) 0th gear (1100Hz to 1600Hz), suitable for use under different conditions. The working principle of the instrument is to rely on the shock wave of a physical sound source to transmit sound, gradually amplifying the sound until it can be heard normally in the ear. The larger the leakage point of the detection pipe, the better the effect. 5SUPER LONG RANGE: Using batteries of 1 x 9V 6F22 (shipped without batteries), consuming a current of 1333 milliamperes, and operating time of 10 to 23 hours (depending on sound strength).Item Type: Water Pipe Leakage MonitorMaterial: Aluminum Alloy, ABS Consumption Current: 13-33 mAUsing Battery: 1 x 9V 6F22 (shipped without battery)Working Hours: 10 to 23 hours (determined by sound strength)Four Segment Sound Selection: 3rd gear (100Hz to 700Hz) 2nd gear (700Hz to 900Hz) 1st gear (900Hz to 1100Hz) 0th gear (1100Hz to 1600Hz)Probe Sensitivity: -60dbSound Amplification Factor: 25000 timesAdditional Features: Function jack, which is a recording and recording function .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Detector1 x Probe1 x Headphones1 x Manual1 x Storage BoxNoteThe probe must be in smoothly contact with the tube surface. When making contact, do not drag the probe parallel to avoid damaging it. When using the probe, adjust the sound gear knobs 0, 1, 2, and 3 to achieve the best effect, and adjust the volume knob to match the conventional 3rd gear.
