Leak detection
The EX-TEC® SNOOPER 4 from Hermann Sewerin, is a high-precision gas detector specially developed for the ppm range. It is ideal for detecting leaks in building pipelines, testing weld seams, and conducting in-house tests. With a measuring range of 0 to 10,000 ppm and a display capacity of up to 22,000 ppm, the device can be configured for both methane (CH4) and hydrogen (H2). The device must be used in a special carrying case in hazardous areas or hydrogen environments to ensure maximum safety.
