103 barometer

Description

Aneroid precision barometer model 103 for the measurement of absolute atmospheric pressure. Precision aneroid barometers are used for measuring the absolute atmospheric pressure. Because of the excellent instrument properties an aneroid barometer is indispensable particularly for meteorology, ocean shipping, industry and research.

The self-stable set of five aneroid capsules, used in our precision aneroid barometers, is made of a corrosion proof copper-beryllium-alloy. This alloy has been well established for measuring the atmospheric pressure since many years because of its remarkable elastic properties. The aneroid capsules are nearly free of age-hardening, hysteresis and elastic after-effects.
