Aneroid  barometers are reliable and exact instruments for quick measurement of atmospheric pressure. Their particular advantages, in comparison to the mercury barometers described in leaflet 111,0E, consist in their good suitability for transportation, their slight weight and requirement of space, as well as their insensibility against shock and vibration, so that they are used also, with preference, aboard ships, in aviation, for measurement of altitude in the open country and when travelling. A further advantage is their independence of indication from gravity and temperature, for which reason corrections as required with mercury barometers become unnecessary.

The measuring element of precision aneroid barometers is a set of several aneroid boxes, which, contrary to their own elasticity, are pressed together in a more or less degree by the varying atmospheric pressure. The motion of the set of aneroid boxes is transmitted to the pointer by a gear-mechanism. The aneroid boxes consist of a special high-grade material of excellent properties of elasticity and, thus, are practically free of hysteresis and elastic after effects. A particular, thoroughly developed bimetallic system effects, independent of the height of atmospheric pressure, an absolute elimination of the influence of temperature so that the respective errors as to indication are avoided. The design of the pointer with edges lying one above the other guaranties parallax-free reading.
