Precision Barometer No. 2039 is designed for accuratedetermination of the absolute air pressure. The metal diaphragms, which aremanufactured in a special technical process, react, very sensitively to changesof the surrounding air pressure.
This barometer determines the absolute air pressure, i.e. the air pressure whichexists at the place of installation. An adjustment such as on normal barometers,which indicates the air pressure reduced to sea level, is therefore unnecessary.The 2039 Barometer is also suitable for exact determination of slight heightdifferences within the range of the dial. All models are jeweled movement.Accuracy ±1.5% of full scale.
Applications: Engine test stations, airports, laboratories,hospitals and many scientific applications where precise measurement of absoluteair pressure is required.
