Trust – the measure of all things
In the course of many decades and against the background of our family tradition perfection and the name HÄFNER have become inseparable terms.
Worldwide trust and recognition through the national metrological institutes - NMIs (e.g. PTB, NPL etc.), accredited calibration laboratories, professional authorities in the official calibration and measurement sector, scale manufacturers, maintenance providers, companies from all sectors of the industry and even competitors confirm our special achievements and our success.
Client requests and requirements for perfect weights demand a constant development process in order to achieve and improve the necessary prerequisites.
HÄFNER has a spacious adjustment and calibration laboratory "MASSCAL", which fulfils the highest metrological requirements. We keep our measurement devices at the current state of the art through our high investments.
MASSCAL is accredited by the DAkkS (Deutsche Akkreditierungsstelle / German Accreditation Body) as a DAkkS calibration laboratory. The internationally valid DAkkS calibration certificates fulfil the requirements for test tool monitoring prove traceability to the national standard.
The special steel HE210 was developed as a further component for the manufacture of the perfect weight that fulfils the requirements of class ‘EO’. National metrological institutes around the world have been placing their trust in their HÄFNER primary standards (class EO) and E1 mass standards for many years.
HÄFNER uses a special laser process to mark weights so that the stability of the measurement value is not endangered. This allows standards of classes E2, E1 and EO to be identified and stops them from being interchanged.
HÄFNER not only fulfils everyday client requirements. Special requests are also very important:
- Very small weights (up to 0.1 mg)
- Very large weights (up to 5000 kg)
- Special types (e.g. load cells, air buoyancy units, basket weights)
- Accessories (e.g. bell bars, weight handling)
- Special containers (e.g. service cases)
We would like to return your trust in HÄFNER with quality and performance. Challenge us!
