What GfG does

GfG - Gesellschaft für Gerätebau mbH, headquartered in Dortmund, Germany, is a privately held manufacturer of gas detection systems founded in 1960 and still owner-managed by Hans-Jörg Hübner. The company designs and produces portable and fixed gas detection equipment for industrial safety, fire and civil protection, semiconductor manufacturing, chemical processing, mining, and refrigeration/cold-storage applications, using four measurement principles: electrochemical, infrared, catalytic, and photoionization (PID). Its product portfolio spans portable detectors (Micro 5, Microtector III G888, Polytector III G999/G999S, TeamLink G999L), fixed-system controllers (GMA22, GMA200-MT, GMA400), transmitters (D-ReX, EC22, IR22 F, CC22/CS22, etc.), water measurement devices, calibration test gases, and customized gas sampling systems and control cabinets; proprietary technologies include ACDC digital-over-analog signal transmission and ATEX/IECEx-certified devices for explosive atmospheres. All product development is retained at the Dortmund R&D headquarters, with >14% of revenue reinvested annually into R&D.

The company operates a B2B industrial equipment business model, generating revenue primarily from hardware sales of portable and fixed gas detection systems, supported by recurring professional services (calibration, maintenance, repair, training via GfG Campus) and consumables (test gases, replacement sensors). Pricing is quote-based, ex-works EUR plus VAT, with project-level consulting and lifecycle support baked into engagements. GfG distributes through 11 wholly-owned international branch offices (Germany, USA, Switzerland, UK, France, Poland, South Africa, Austria, Netherlands, Singapore, Taiwan) plus a network of local sales partners, and actively participates in major trade fairs (A+A, INTERSCHUTZ, SEMICON, Chillventa). The customer base is diversified across industrial safety, semiconductor fabs, chemical, mining, municipalities, fire/emergency services, and cold-storage — with no single named customer dominating. Reported scale signals include ~350 employees worldwide (168 in Dortmund), ~20.21% YoY revenue growth as of February 2026, and ISO 9001:2015, ATEX, and IECEx certifications.

Core offering

GfG develops, manufactures, and sells gas detection systems for industrial and occupational safety, comprising portable single- and multi-gas detectors for personal worker protection and fixed gas warning systems built from controllers and transmitters for continuous facility monitoring. The portfolio also covers water-leak monitoring for cooling circuits, calibration test gases, accessories, gas sampling systems, respiratory air monitors, and supporting services such as maintenance, training (GfG Campus), commissioning, and consulting across the product lifecycle.

Product overview

GfG offers a comprehensive portfolio of gas detection products and systems centered around two core product lines: portable gas detectors (including Micro 5, Microtector III G888, Polytector III G999, TeamLink) and fixed gas detection systems comprising controllers (GMA22, GMA200-MT, GMA400) and transmitters (D-ReX, CC22, CS22, EC22, IR22, ZD22, CC28, EC28, IR29, CC33 series). The portable detectors provide personal protection for individual workers, while the fixed systems enable facility-wide monitoring through a controller-transmitter architecture where transmitters detect gases and relay data to centralized controllers. Supporting products include water measurement technology, accessories, test gases, and gas sampling systems. The product range covers detection of toxic gases, flammable gases, oxygen deficiency, and specialty applications including semiconductor manufacturing (D-ReX), cold storage (IR22 F), and helium environments (EC22 O).
