Core offering

SEWERIN (Hermann Sewerin GmbH) develops, manufactures, and sells precision measuring and detection devices for water leak detection and gas leak detection. The product portfolio spans acoustic leak locators (correlators, noise loggers, ground microphones), laser-based (TDLAS) methane detection systems, gas warning and measuring devices, and bio/process gas analyzers. These devices are used by water suppliers, gas utilities, and pipeline operators to inspect underground pipe networks, locate leaks, and comply with regulations such as the EU Methane Emissions Regulation.

Product overview

SEWERIN (Hermann Sewerin GmbH) is a German manufacturer of precision measuring and detection equipment with over 100 years of industry experience. The company offers a comprehensive portfolio of products organized into four main categories: Water (leak detection and monitoring), Gas (detection, measurement, and warning), Bio & Process Gas (stationary and mobile analyzers), and Detection (pipe and object location). The Water portfolio includes acoustic leak detection systems like the AQUAPHON A 200 and A 150, the multi-function SeCorrPhon AC 200, correlators (SeCorr C 200), noise loggers (SePem 351/150/100), and ground microphones (AquaTest T10, Stethophon 04). The Gas portfolio features vehicle-based LaserGasPatroller systems (LGP 800 and LGP 900) for automated pipe network inspection, remote laser detectors (SR-LD 800/200), multi-function devices (EX-TEC PM 580, EX-TEC HS 680), and portable detectors (PORTAFID M3-K, SNOOPER mini). The Bio & Process Gas line includes the Multitec 560 mobile analyzer. These products serve water suppliers, gas utilities, pipeline operators, municipalities, and service companies through a global network of authorized distribution and service partners.
