The Stethophon 04 can be equipped with either wired headphones or with Sewerin SDR wireless headphones. Sewerin SDR wireless digital signal processing technology prevents acoustical interference, e.g., hissing, re-amplifying, etc. Every Stethophon 04 feature user-selectable audible filter functions, enabling users to listen to the sound frequency of the leak noise while filtering nuisance noises.

    XLT-100

    The XLT-100 compact leak detector is an affordable leak survey device. It offers an attached contact microphone (no ground mic).

  • Acoustical & Pipe Locating (building solution)

    A ready-to-use solution for water both pipe locating and water leak detection in buildings.

    Aquaphon AF50/FG50

    The Sewerin Aquaphon AF50/FG50 is a complete package solution based on the Aquaphon A50 and Ferrophon series. It offers the leak detection professional a range of possibilities for precisely locating pipe and water leaks in buildings, all within a single piece of equipment.

  • (H₂) Gas Tracer System

    Tracer Gas is the best method when acoustical cannot achieve results. Tracer gas is not susceptible to ambient noise interference and will surface directly above the leak.

    Variotec 460

    The Sewerin Variotec 460 leak detector locates leaks when acoustical systems cannot, e.g., extremely deep pipe, loud ambient industrial sites, or newly installed water systems not passing pressure testing. Detecting water leaks using tracer gas involves injecting a mixture of 95% nitrogen (N₂) as carrier gas and 5% hydrogen (H₂) as the traceable/detectable agent. The H₂ gas escapes through the leak and is detected above ground by the Variotec 460 instrument's specialized sensor. H₂ tracer gas is non-toxic and non-corrosive, therefore permitted for use in all drinking water systems. H₂ tracer gas is environmentally neutral and permeates all cover layers such as asphalt, concrete, and other seal coats. Hydrogen (H₂) is the lightest and smallest known element on the periodic table; therefore, it will always take the shortest route from the leak to the surface, making pinpointing a water leak on any surface possible.

  • Leak Correlators

    Leak Correlators are perfect for systems where users know there is a leak but cannot pinpoint it. Correlators can save a lot of time on a big job.

    SeCorr C200

    The SeCorr 200 water leak correlator from Sewerin is the newest and most capable leak correlator. The SeCorr C200 platform offers a large 5.7" high-resolution VGA display, a touchscreen compatible with gloves.

Wireless headphones provide a complete "cable-free" operation. 

    SeCorrPhon AC200

    The SeCorrPhon AC200 from Sewerin is a multifunctional professional leak detection system from Sewerin, combining the industry's best acoustical leak detector (Aquaphon A200) with the industry's best water leak correlator (SeCorr C200). All fit into a single ruggedized carry case featuring a single mains plug-in to recharge all components simultaneously. The AC200 controller becomes an acoustical leak detector or a water leak correlator with just a button press and microphone choice. For any professional looking for the best complete leak detector system on the market today, look no further than the SeCorrPhon AC200.

    SeCorr 300

    The SeCorr 300 from Sewerin is a PC-based water leak correlator. The system utilizes the powerful SeCorr 300 software combined with the high-performance RT300 transmitters to produce significant advantages, particularly when used with HY200 Hydrophones on plastic pipe applications, where noise emitted from the leaks is difficult to detect. The PC software will provide improved coverage on plastic pipe applications. The SeCorr 300 includes a rugged carry case with a single plug-in recharging cord for the transmitters.

  • Noise Loggers

    Loggers are perfect for active leak detection programs. Deploy and pick up later, and the logger will let you know if leaks are present. Ideal for large leak programs but with small crews. Loggers keep working while employees are off duty.

    SePem 155

    The Sewerin SePem 155 radio noise loggers are the latest in logger technology. The SePem 155's offer class-leading performance and construction. The stainless steel and durable plastic design meet IP68 standards. They are waterproof and resistant to corrosion, making them suitable for all water distribution systems. SePem 155 loggers come standard with long-life batteries (many years), powerful magnets for attaching to valves, and class-leading sensitivity with its Piezo microphone optimized for water leak detection sounds. SePem 155 can deploy in both the popular "Lift & Shift" applications or semi-permanent "Patrol" applications. Noise loggers are ideal for deployment overnight and listening for leaks between 2:00 am - 4:00 am, where activity is minimal. The SePem 01 Master controller programs SePem 155 loggers. The SePem 01 master controller is a hand-held device that can also mount into a vehicle bracket for "Patrol" applications. During Patrol mode or "Drive-by," the SePem 01 controller will automatically communicate with the loggers as they come into range via its bidirectional radio link and indicate both via an audible tone and visual display if a leak is indicated or detected. Information such as "Minimum Noise Level" and "Noise Consistency" will be highlighted on display for easy user analysis. Loggers that record no leak noise will indicate zero (-0-). Each SePem 01 Master controller can accommodate up to 500 SePem 155 loggers.
