What GMC-I PROSyS does

GMC-I PROSyS Ltd. is a UK-based designer and manufacturer of sensors, instruments, and systems for electrical parameter measurement, founded in January 2008 as a wholly-owned subsidiary of METRAWATT International (now GMC Instruments Group) and headquartered in Skelmersdale, Lancashire. The company specializes in non-intrusive current and voltage measurement technologies built on Hall-Effect (open and closed loop), Rogowski principle, and Fluxgate techniques, protected by patented magnetic circuits and a patented split-core mounting bracket. Its hardware portfolio spans AC/DC current probes (CP Series), flexible Rogowski probes (PRO~flex and MICRO~flex up to 6,000 A), AC/DC split-core transducers (AT/FT/FTDC Series), DIN-rail-mounted flexible probes (DRM/DRP), and the METSyS NEC 220 current logger, complemented by the December 2023 launch of the DACP range with MODBUS communications for substation monitoring.

The company's revenue is generated primarily through hardware sales via a global channel-led model, with customized OEM solutions serving as a higher-touch, design-in revenue stream for automotive, electrical utility, energy management, and test & measurement customers. Standard products are distributed through regional partners across Africa (South Africa), Asia (India, South Korea), Australia, Europe (Germany), North America, and South America (Brazil), while customized OEM work is supported by direct enterprise field sales. Pricing is quote-based and not publicly disclosed, and additional revenue comes from professional services such as repair, calibration, and returns handling. The product mix is complemented by a free mobile companion app (iOS/Android) and Excel-based Maximum Demand reporting software, intended to deepen engagement with the METSyS logger ecosystem rather than serve as standalone revenue drivers.

GMC-I PROSyS holds ISO 9001 certification (ISOQAR, 2024), Achilles UVDB Silver Plus certification (2025), GAMBICA trade association membership, EN 50121-1 rail EMC compliance, IEC 62020-1 residual current monitoring accreditation, and RoHS/REACH compliance statements — collectively positioning it for utility, rail, and industrial procurement channels. As a subsidiary within the broader GMC-I Group, it benefits from cross-brand distribution alongside sister companies including GMC-I Messtechnik, Camille Bauer, Gossen Metrawatt, Dranetz, Seaward, and others, while retaining a focused product portfolio centered on electrical parameter sensing.

Core offering

GMC-I PROSyS designs, develops, and manufactures current probes, clamp meters, handheld instruments, and systems for current and voltage measurement, along with processing of electrical parameters. The portfolio spans AC/DC current probes (Hall-Effect), flexible Rogowski coil probes, split-core current transducers, current data loggers, and MODBUS-enabled Rogowski sensor monitoring equipment, sold both as standard catalog products and as customized OEM solutions for automotive, electrical utility, energy management, and test & measurement customers.

Product overview

GMC-I PROSyS is a manufacturer of electrical measurement sensors and instruments organized into two main categories: hardware products and software solutions. Hardware products include the CP Series (AC/DC current probes and clamp meters using Hall-Effect technology), PRO~flex and MICRO~flex flexible AC current probes (using Rogowski technology for up to 6000A), AC/DC Split Core Current Transducers (AT/FT/FTDC series), AC Current Probes (transformer-based), DRM/DRP series (DIN rail mounted flexible probes), Rogowski Coils/Rope CTs, the METSyS NEC 220 Current Logger (4-phase datalogger), and the DACP range (Rogowski sensor monitoring equipment with MODBUS). Software includes the METSyS Current Logger App (iOS/Android Bluetooth companion app) and Maximum Demand Report Writing Software (Excel-based analysis tool). The company also offers Customized/OEM Solutions for automotive, utilities, energy management, and test & measurement applications. Key technologies include Hall-Effect, Rogowski principle, Fluxgate, and patented magnetic circuits.
