Aneroid barographs are used to measure and record the history of atmospheric pressure. The measuring element in our barographs is a set of 7 aneroid capsules with a diameter of 62 mm. This set is manufactured of a copper-beryllium alloy that essentially eliminates age-hardening, hysteresis, and elastic after effects that could otherwise degrade the accuracy. The influence of temperature on the set of aneroid capsules and the transmission system is compensated by use of bimetal components over the full measuring range and for temperatures between -30 to +40 °C (-22 to 104 °F). All contacts in the movements are jeweled to reduce friction. Fischer barographs are used by navies and weather services, worldwide. Fischer instruments are unique in offering an option on each model with enhanced dampening for barograph use at sea. After you chose your model and timing option, the extra dampening can be selected. There is no need for this option for land based operations. The paper charts are the same size for all models: 92mm tall by 302 mm long. Charts marked in inches of mercury are also available on request.
