Core offering

KoCoS designs, develops, and manufactures precision measurement and test systems across two domains: electrical metrology (circuit breaker testing, resistance measurement, protection relay testing, power quality analysis, digital fault recording, AC/DC power sources, and meter testing) and optical metrology (wafer edge profile measurement, 3D inspection, vacuum inspection of containers, and catalytic converter measurement). Products range from portable handheld devices to stationary laboratory systems and are complemented by proprietary software platforms (ACTAS EXPERT, ARTES 5) and engineering services with training courses.

Product overview

KoCoS Messtechnik AG offers a comprehensive portfolio of electrical and optical metrology solutions. The electrical metrology division includes ACTAS (circuit breaker testing systems), PROMET (resistance measurement/micro-ohmmeters), ARTES (protection relay testing), SHERLOG (digital fault recording), EPPE (power quality analyzers), EPOS (power sources), and METES (meter testing). The optical metrology division features WATOM (wafer edge profile measurement), LOTOS (3D measurement), INDEC (vacuum inspection), and OMCAT (catalytic converter measurement). The company also provides Engineering & Services and training. Products range from portable handheld devices to stationary laboratory systems, with associated software platforms like ACTAS EXPERT and ARTES 5 for data analysis and test management.

Targets commissioning and maintenance engineers in power utilities and industrial protection applications.
• SHERLOG Digital Fault Recorders Fault recorder systems with integrated power quality analyser for comprehensively monitoring and assessing low, medium, and high voltage networks in power plants. The SHERLOG CRX variant has received approvals from Saudi Electricity Company and Swedish National Grid (Svenska Kraftnät) for power network monitoring.
• EPPE Power Quality Analyzers Power quality measuring systems with integrated fault recorder functionality for continuously and automatically monitoring electrical installations. Includes EPPE RX for DIN rail mounting. Used by utilities and industrial facilities to monitor power quality and detect disturbances.
• EPOS AC/DC Power Sources AC/DC power sources for supplying and testing motors and release coils on switching devices. Product line includes EPOS 360 (three-phase signal generator), EPOS MC4 (portable motor and coil testing system, IP67 rated), and EPOS CV 201 (electronic voltage source launching early 2026). Uses synthetic power electronics for interference-insensitive output.
• METES Meter Test Systems Extensive range of portable meter test systems of various types, all developed and manufactured by KoCoS. Used for electricity metering validation by utilities and meter testing laboratories.
• WATOM Wafer Edge Profiler Wafer edge profiler using patent laser technology for quality assurance and process control of edge grinding and polishing processes. Sets the worldwide benchmark, measuring edge profiles at any circumference point including inside the notch with measurement precision below 1.5 µm. Used by leading wafer manufacturers globally.
• LOTOS 3D Measurement and Inspection System 3D measurement and inspection system that measures full outer and inner contours or individual areas of any measurement object and tests them for defects. Used for geometric inspection and defect detection in industrial production environments.
• INDEC Vacuum Inspection Systems Vacuum test systems for non-contact, 100% inline inspection of containers (bottles, jars, cans) during production by measuring cap panel concavity dependent on the vacuum inside. Includes the INDEC VD 400 launching in early 2026 with material/color/surface-independent laser sensing.
• OMCAT Catalytic Converter Measurement Systems Catalytic converter measuring systems for fast and efficient complex geometrical measurements on exhaust catalytic converters and determining gap bulk density (GBD). Serves automotive exhaust after-treatment manufacturers.
• Engineering & Services Comprehensive range of measurement and test services for planning reliability and core task support. Includes engineering and testing services delivered to industrial and utility customers.
• Training Courses and Webinars Training courses, practical seminars, and webinars covering KoCoS products such as PROMET L100s and EPOS MC4. Includes free webinars and structured training programs for customer teams.

Direct peers

• Megger Group: Global manufacturer of electrical test and measurement equipment including insulation testers, micro-ohmmeters, and circuit breaker analyzers. Overlaps directly with KoCoS's PROMET and ACTAS product lines for utilities and industrial electrical testing.
• Hioki E.E. Corporation: Japanese manufacturer of electrical measuring instruments including power meters, micro-ohmmeters, and recorders. Comparable to KoCoS's PROMET, EPPE, and SHERLOG product lines for power engineering and electrical metrology customers.
• OMICRON Electronics: Austria-based specialist in protection relay testing, power quality analysis, and electrical metrology for utilities. Direct competitor in ARTES's core market of protection relay test systems, with overlapping product lines in protection testing and power quality.
• KWS Electronic Test Equipment: German manufacturer of test equipment for circuit breakers, protection relays, and rotating machines. Direct European competitor in the same switchgear testing category where KoCoS claims market leadership.
• Doble (ESCO Technologies): Provider of diagnostic testing and monitoring solutions for the electric power industry, including protection relay and circuit breaker testing. Closely comparable to KoCoS's switchgear and protection relay testing focus on utility customers.

Broad incumbents

• SAT (Schweitzer Engineering Laboratories): US-based provider of protection relays, automation, and monitoring solutions for electric power systems. Adjacent competitor with broader portfolio covering protection, automation, and metering that touches KoCoS's relay testing and power quality offerings.
• ZEISS Industrial Metrology: Provider of industrial measurement and inspection solutions including 3D coordinate measuring and optical systems. Comparable to KoCoS's LOTOS 3D measurement and inspection product line as a broader industrial metrology platform.
• KLA Corporation: Major semiconductor process control and yield management equipment provider. Comparable to KoCoS's WATOM wafer edge profiler as a semiconductor metrology player, but operating at vastly larger scale across inspection and metrology.
• Lasertec Corporation: Specialist in semiconductor mask blank and wafer inspection equipment using advanced optics. Adjacent to KoCoS's WATOM laser-based wafer edge metrology business, serving the same semiconductor fab customer base.
• Fluke (Fortive Corporation): Broad-line test and measurement brand under Fortive covering electrical, industrial, and calibration instruments. Competes with KoCoS in micro-ohmmeters and power quality tools, but as part of a much larger multi-category portfolio.
