Description

To most experts, this is one of the highest quality aneroid barometers in the world. It has been tested at sea for over 70 years, and used by Navies and Weather Services around the world, including the NWS Voluntary Observing Ship program. The double needle design removes parallax error in reading. Every instrument has a unique serial number with certificate of accuracy.The self-stable set of five aneroid capsules, used in this precision instrument are made of a corrosion proof copper-beryllium-alloy. This alloy has been well established for measuring the atmospheric pressure for many years because of its remarkable elastic properties. The aneroid capsules are nearly free of age-hardening, hysteresis, and elastic after-effects. See specifications for details.
