What Haenni Scales does

HAENNI Instruments AG, operating as Haenni Scales, is a Swiss manufacturer of mobile wheel load scales and weighing systems used to determine the weight of heavy goods vehicles. Founded in 1919 as Haenni & Cie AG (originally a manometer and fittings factory) and producing wheel load scales since 1974, the company is headquartered in Kirchberg, Switzerland and has been a wholly-owned subsidiary of Baumer Group since 2005. Its product line includes the mechanical WL 101, electronic WL 104, wireless WL 108, and dynamic strip sensors WL 400/WL 401, complemented by the EC 120 processing unit and EC 200 certified evaluation software. Core technology is built around patented spring-element load cells, certified to OIML R 76 class IIII, EU Type approval, and NIST H44, with products designed for 30-40+ year operational lifespans.

The company serves four primary verticals: government authorities (police, customs, military, road traffic offices for enforcement and border control), industrial manufacturers (tire, special-vehicle, and crane makers for testing and load distribution), transportation and logistics operators (haulage companies, seaports for SOLAS VGM certification), and research/testing institutes (metrology labs, road concessionaires). It generates revenue primarily through hardware sales of scales, sensors, processing units, and accessories, supplemented by licensing of EC 200 evaluation software and service offerings including legal-metrology verification, calibration, training, and equipment rental. The go-to-market combines direct sales from headquarters (Kirchberg) with a network of qualified representatives in 100+ countries, and pricing is quote-based via inquiry forms rather than publicly disclosed.

HAENNI holds ISO 9001:2015 certification (SGS-audited), operates under Baumer's Lean Six Sigma / Baumer Operations Systems, and is an active member of EUMOS, IRF, CECIP, and the Swiss Weighing Association. With 11-50 employees and an installed base of over 30,000 WL 101 units worldwide, the company occupies a defensible niche at the intersection of legal metrology, road-safety enforcement, and logistics compliance, with growing relevance to dynamic Weigh-in-Motion applications.

Core offering

Haenni Scales designs, manufactures, and sells mobile wheel load scales and vehicle weighing systems used for road weight enforcement, industrial vehicle testing, and research applications. Its product range includes mechanical scales (WL 101), electronic scales (WL 104, WL 108), strip sensors (WL 401), processing units (EC 120), and evaluation software (EC 200), sold with accessories and configuration options for diverse customer needs.

Product overview

HAENNI Instruments AG, a Baumer Group company based in Switzerland, offers a portfolio of mobile wheel load scales and weighing systems for vehicle weight enforcement. The product line consists of wheel load scales (WL 101, WL 104, WL 108), wheel load strip sensors (WL 401), processing units (EC 120), and processing software (EC 200). These products work together as weighing solutions: wheel load scales measure individual wheel and axle weights, processing units (EC 120) collect and display readings with integrated printing capability, and processing software (EC 200) enables comprehensive data analysis on Windows PCs. Solutions range from minimal static weighing systems to dynamic Weigh-in-Motion (WIM) configurations. Accessories including cables, leveling mats, and remote displays complement the core product range.
