Aneroid barometer for the measurement of the absolute atmospheric air pressure. Precision measuring unit with 5-fold aneroid set of copper-beryllium alloy, inherently stable.
Measuring range 890 to 1050 hPa
Measuring accuracy ± 0.7 hPa
Scale division 0.5 hPa.
The aneroid doses are virtually free from aging, hysteresis and elastic aftereffects. The temperature influence on the kit and the transmission system is compensated by a bimetal over the entire measuring range and in a temperature range of -30 to +40 ° C. The transfer of the can stroke to the pointer axis is done by means of drive and segment with the finest teeth. All bearings are finely polished. Due to the advantageous design of linkage and bearings, the instruments have only a minimum resting friction.
Case polished brass or chrome plated, diameter 165 mm. Mineral glass cover.
Delivery time: appr. 10 working days.
"Fischer aneroid from Germany, with a 5.5" dial and a 5-cell movement is among the best of the aneroids available today. This instrument has an accuracy of better than + -0.7 mb over its full working range of 890 to 1050 mb. Fischer aneroids have been at sea for 60 years. " David F. Burch, PhD, Director of the Starpath School of Navigation Seattle USA
