F.E.S.

What F.E.S. does

F.E.S. GmbH is a privately held German calibration laboratory headquartered in Alzenau near Frankfurt, with a second accredited laboratory in Dippoldiswalde near Dresden. Founded in 1986 by Dipl.-Ing. Ulrich Löffler and Dipl.-Ing. Klaus Englert, the company provides DAkkS-accredited and factory calibration services for electrical measurement quantities, and historically also dimensional and mechanical measurement quantities (the latter scope was divested in July 2023 along with the Wendlingen location). Its services target the electrical and electronics industry, mechanical engineering, and telecommunications, and include in-lab calibration, on-site mobile calibration across Germany using dedicated calibration vehicles, pickup and return logistics, repair services with warranty, and complete test equipment management. The company also offers calibration of virtual instruments (PXI, PXIe, PCI, USB data acquisition modules).

The firm's proprietary technology stack centers on MetSoft, a registered software brand comprising MetSoft CALIBRATION (for managing calibration of electrical, dimensional, mechanical, and physical measurement quantities) and MetSoft OBJECTS (a quality management module for test equipment administration). This software is used both internally and licensed to customers to support calibration workflows, documentation, and quality management system integration. The core regulatory moat rests on DAkkS accreditation D-K-17522-02-00, originally granted in 1991/1992 and re-accredited under DIN EN ISO/IEC 17025:2018, which provides traceable calibration certificates required by many industrial customers.

F.E.S. operates as a B2B professional services and software licensing business. Revenue is generated primarily through fee-for-service calibration engagements (quoted per device per service), supplemented by MetSoft licensing and a smaller repair services stream. The go-to-market is sales-led and direct: customers engage via phone, email, or the company website's contact form for quotes, with no public pricing, no published tiers, and no self-service digital channel. The company employs 11-50 staff and exhibits classic small-cap characteristics: founder-led management (Löffler remains Managing Director), regional single-country footprint (Germany), and a concentrated vertical focus on industrial measurement-intensive customers.

Core offering

F.E.S. is a DAkkS-accredited calibration laboratory offering calibration of electrical, mechanical, dimensional, and temperature measurement instruments for industrial customers. The company complements its calibration services with proprietary MetSoft CALIBRATION and MetSoft OBJECTS software for managing calibration data and test equipment records, and operates mobile on-site calibration and pickup-and-return services in addition to its in-lab calibration.

Product overview

F.E.S. GmbH operates a dual product model consisting of proprietary software and calibration services. The MetSoft software suite comprises two main products: MetSoft CALIBRATION for calibration management of electrical, dimensional, mechanical, and physical measurement quantities, and MetSoft OBJECTS for quality management and test equipment administration. These software tools are complemented by a comprehensive range of calibration services including DAkkS-accredited calibrations, factory calibrations, on-site mobile calibrations, pickup/return logistics, test equipment management, repair services, and calibration of virtual instruments (data acquisition cards and PXI systems). The software supports web-based functionality and is designed for compatibility with customer systems.

• QS Grimm GmbHcoreStrategic or Co-development Partner · 1 July 2023In July 2023, F.E.S. sold its Wendlingen location (dimensional metrology business unit) to QS Grimm GmbH. A cooperation agreement was signed to intensify future collaboration. Both companies are DAkkS-accredited and will offer accredited calibrations (F.E.S.: D-K-17522-02-00; QS Grimm: D-K-15159-01-01 and D-K-15159-01-02) as well as factory calibrations. The goal is to expand service offerings in calibration, contract measurements, and repair services.
