r : r > R, Type empty The box barometer (plain type) and the empty box barometer (plateau type) are driven by the axial displacement caused by changes in atmospheric pressure. The pointer mounted on the pointer shaft is driven on the dial through the crank link mechanism and gear transmission mechanism. Make a circular motion. The value indicated by the pointer on the dial is the atmospheric pressure value at that time.
R, empty box barometer is used in meteorological stations and other relevant departments to measure atmospheric pressure.
R,
R, main technical indicators:
R, measuring atmospheric pressure range: ~ ( Plain type), (plateau type).
R, operating temperature range: +℃ (plain type) +℃ (plateau type).
R, instrument thermometer scale range: +℃ (plain type) +℃ (plateau type).
R, the minimum scale value of the instrument temperature: ℃.
R, after indication, temperature and supplementary correction, its measurement error: +/.
R, Minimum graduation value of dial:.
R, Instrument weight:.
