What Metrus does

METRUS GmbH is a German specialist manufacturer of valve and armaturen test benches, headquartered in Erkelenz and tracing its origins to LS-Mechanik Lothar Seer KG founded in 1970. The company designs and builds stationary and mobile test benches for pressure testing, leakage testing, and functional testing of control valves, shut-off valves, safety valves, and butterfly valves across nominal sizes from DN10 to DN800 and pressure ranges from vacuum to 1,600 bar water / 600 bar air. Its product portfolio spans the CSV, SV, SVM, and BV series, project-specific ATB automated test systems, mobile units (VTM, MPU 600), precision instruments (Laser Bubble Counter, Flow Meter Cascade, Setpoint Adjuster, Seatinspec visual leak testing), and proprietary CRS test bench software with WIKA sensor integration, MySQL / Microsoft SQL database support, and optional ERP connectivity.

The company generates revenue primarily through one-time sales of custom-engineered test benches and special-purpose machines, supplemented by service, maintenance, calibration, and on-site commissioning contracts. Customers include industrial valve manufacturers, valve service and maintenance companies, and end-user plants in oil & gas, chemical processing, power generation, and general manufacturing. Notable clients include SAMSON AG, LESER, KÜHME, MANKENBERG, KLINGER Fluid Control, Goetze, AVA Gruppe, TECTRION, Infraserv Höchst, Allied Oil & Gas Service, Fragua E&P, and ISI Control, with an installed base spanning more than 20 countries across Europe, Asia, the Middle East, Africa, and North America. Distribution is direct enterprise field sales with a dedicated service technician team for field maintenance and commissioning.

In 2025, METRUS was acquired by TRIATOS Capital from Johannes Junior, with Thomas Kamphausen assuming the role of sole Managing Director. The company holds DIN EN ISO 9001:2015 certification and positions itself around "Made in Germany" precision engineering, international standards compliance (EN 60534-4, EN 12266, API 527, ANSI FCI70-2, DIN 3230), and a 55-year track record of innovation including the first fully automatic test bench in 1986 and the first computer-controlled test bench in 1988.

Broad incumbents

• SAMSON AG: SAMSON is one of the world's largest valve manufacturers and a long-standing METRUS customer (multiple test benches across global operations). Both companies serve the industrial valve market with high-quality German engineering, though SAMSON is primarily a valve maker while METRUS is a test bench specialist; their relationship is both customer-vendor and adjacent competitor in control valve testing.
• Curtiss-Wright Corporation: Curtiss-Wright is a US-based diversified industrial manufacturer with a Defense and Power & Energy segment that includes testing and measurement equipment. While serving a broader portfolio including aerospace and defense, the company's industrial testing systems compete with METRUS in high-pressure industrial and valve testing applications at much greater scale.
• Emerson Electric Co. (Valve Automation): Emerson is a global industrial automation leader whose valve automation and control products serve the same oil & gas, chemical, and power end markets as METRUS. While primarily a valve and automation supplier, Emerson competes with METRUS indirectly through integrated testing and diagnostic solutions for industrial valves.
• WIKA Alexander Wiegand SE & Co. KG: WIKA is a global leader in pressure and temperature measurement, and a technology partner to METRUS (native integration of WIKA CPT2500 USB pressure sensor in Free CRS software). Both serve industrial pressure measurement and calibration markets, though WIKA operates at a much broader scale as a component supplier to METRUS and other test bench makers.

Direct peers

• Hydrotechnik GmbH: Hydrotechnik is a German manufacturer of measurement and test equipment for hydraulic and fluid power applications. The company produces pressure testing, leak testing, and functional test systems for valves, cylinders, and hydraulic components — closely overlapping with METRUS's industrial valve and pressure vessel testing portfolio.
• LESER GmbH & Co. KG: LESER is a leading global safety valve manufacturer and a key METRUS customer (e.g., LESER Polska). Both companies focus on safety and industrial valve testing equipment, with LESER being both a buyer of METRUS test benches and a developer of its own safety valve test protocols, making them closely comparable in the safety valve testing niche.
• Cincinnati Test Systems: Cincinnati Test Systems is a US-based manufacturer of leak testing and pressure testing equipment for automotive, industrial, and medical applications. The company competes with METRUS in pressure and leak testing instrumentation, particularly for production-line integration, making it a direct peer in industrial leak and pressure test bench solutions.
• ATEQ (Leak Testing): ATEQ is a global specialist in leak testing equipment and instruments for industrial, automotive, and medical applications. Both ATEQ and METRUS focus on precision leak detection and pressure testing — METRUS for valves and armaturen specifically, ATEQ more broadly — making them directly comparable in industrial leak testing instrumentation.
• Maximator GmbH: Maximator is a German manufacturer of high-pressure technology, including high-pressure pumps, compressors, and test equipment used in oil & gas, chemical, and industrial applications. Both companies serve high-pressure testing markets with German-engineered equipment, and Maximator's high-pressure systems overlap with METRUS's 1,600 bar water testing capabilities.
• Bopp & Reuther Messtechnik: Bopp & Reuther is a German manufacturer of industrial measurement and testing equipment for flow, pressure, and valve applications. The company produces calibration benches and test rigs for industrial valves, directly competing with METRUS in the European valve test bench market with similar German-engineering positioning.
