With sensitivity rated at 7.5 times higher than conventional models, the LD-20 helps operators identify smaller or quieter leak sounds that may otherwise be difficult to detect. Its frequency range of 100 to 5,000 Hz and adjustable filtering options allow the user to tune the instrument for changing pipe conditions and surrounding noise levels.\u003c\/p\u003e\n\u003cp\u003eThe LD-20 features a graphic LCD display with backlight, a compact 600 g amplifier, and a configurable layout that supports left- or right-hand operation by adjusting the display orientation and pickup sensor connection. Recorded sound data can be synchronized with the Android mobile application for analysis and documentation. The system includes a ground mic, magnet base, 3-section rod, aviation-grade stereo headphones, padded carrying case with waist strap, and an ABS custom case for secure transport.\u003c\/p\u003e\n\u003ch5\u003eIn the Box\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eAmplifier w\/LCD, \u0026amp; Control Panel\u003c\/li\u003e\n\u003cli\u003ePadded case for amplifier\u003c\/li\u003e\n\u003cli\u003eMagnet base for Ground Mic.\u003c\/li\u003e\n\u003cli\u003eGround mic\u003c\/li\u003e\n\u003cli\u003eAviation-grade stereo headphones\u003c\/li\u003e\n\u003cli\u003eHand switch\u003c\/li\u003e\n\u003cli\u003eNut driver\u003c\/li\u003e\n\u003cli\u003e3 section rod\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eBrochures and Manuals\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca rel=\"noopener\" title=\"SubSurface Instruments LD-20 Water Leak Detector Product Datasheet\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0694\/0337\/7960\/files\/SubSurface_LD-20_Water_Leak_Detector_Product_Datasheet.pdf?v=1780581556\" target=\"_blank\"\u003eLD-20 Water Leak Detector Product Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca rel=\"noopener\" title=\"SubSurface Instruments LD-20 Water Leak Detector User Manual\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0694\/0337\/7960\/files\/SubSurface_LD-20_Water_Leak_Detector_User_Manual.pdf?v=1780581557\" target=\"_blank\"\u003eLD-20 Water Leak Detector Product Manual\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SubSurface Instruments Inc.","offers":[{"title":"Default Title","offer_id":51926249275688,"sku":"LD-20","price":5650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/0337\/7960\/files\/SubsurfaceLD-20WaterLeakDetectorSystem.jpg?v=1780581508","url":"https:\/\/benchmarksupply.com\/es\/products\/subsurface-ld-20-leak-detector","provider":"Benchmark Tool \u0026 Supply","version":"1.0","type":"link"}
