GANN Mess

What GANN Mess does

GANN Mess- und Regeltechnik GmbH (legally registered in Stuttgart, headquartered in Gerlingen, Germany) is a family-owned manufacturer of handheld electronic moisture and temperature measurement instruments sold under the proprietary Hydromette® brand, which the company has produced continuously since 1948. The product portfolio comprises standalone, multi-electrode, and Kombi devices that apply resistance-based, capacitive, and infrared measurement principles, along with Pt100 temperature sensing, to detect moisture in wood, construction materials, and air. Supporting the devices is a broad accessory ecosystem — including ram-in and drive-in electrodes (M 18, M 20 series), conversion kits (e.g., M 20-DS 16-i), carrying cases, calibration services, and CM-method devices — designed to lock customers into the GANN measurement platform.

The company serves professional buyers across multiple verticals: construction firms, wood processors (sawmills, carpenters, parquet installers), painters and interior finishers, climate technicians and water damage remediation specialists, insurance companies, and architects/housing companies. Its go-to-market is overwhelmingly direct: customers request quotes through the website's 'Produkt anfragen' inquiry function, sales are handled by an internal team, and the website is offered in German and English with metric/imperial unit switching for international reach. Marketing is content-led (multi-language website, PDF catalog, newsletter 1–3 times per year, YouTube demonstrations, SEO), supplemented by occasional event/tradeshow presence.

Revenue mechanics are hardware-centric, with four streams: device sales (the primary driver across Blue, Compact, and Classic series such as CH 17, BL E, BL H 40, BL HT 70, BL A plus, BL Compact B 2, UNI 2, H 35, HT 65, HB 30, HT 85 T, RTU 600), accessories and consumables (electrodes, spare parts, electrode tips, cases), factory calibration services, and repair services. Pricing is quote-based and not publicly disclosed. The firm is privately held, managed by Managing Directors Ulrich Gann and Michael Gann, with no external investors, subsidiaries, or M&A activity disclosed, and operates with 11–50 employees.

Product overview

GANN Mess- und Regeltechnik GmbH offers a comprehensive portfolio of handheld moisture and temperature measuring devices under the Hydromette® brand, developed and manufactured exclusively in Germany since 1948. The product line includes Standalone devices (single-purpose with fixed sensors), Multi-Electrode devices (connect various measurement probes), and Kombi devices (covering multiple application areas). Core products include the Hydromette CH 17 (all-in-one multi-functional), BL E (multi-purpose construction/wood/temperature), BL H 40/42 (wood moisture), BL HT 70 (wood/temperature), BL A plus (capacitive+resistance wood), BL Compact B 2 (capacitive construction), UNI 2 (construction/air humidity/temperature), and classic series devices (H 35, HT 65, HB 30, HT 85 T, RTU 600). The ecosystem is supported by compatible electrodes (M 18, M 20, M 6 series), data loggers (Klima 30), CM devices, carrying cases, cables, and calibration services. Products use resistance-based and capacitive measurement principles without AI capabilities.
