1、PRODUCT 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. 2、APPLICABLE 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. 3、FINE 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. 4、4 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. 5、SUPER LONG RANGE: Using batteries of 1 x 9V 6F22 (shipped without batteries), consuming a current of 13‑33 milliamperes, and operating time of 10 to 23 hours (depending on sound strength). Item Type: Water Pipe Leakage Monitor Material: Aluminum Alloy, ABS Consumption Current: 13-33 mA Using 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: -60db Sound Amplification Factor: 25000 times Additional Features: Function jack, which is a recording and recording function 1 x Detector 1 x Probe 1 x Headphones 1 x Manual 1 x Storage Box
