Air pressure is the atmospheric pressure acting on a unit area, which is equal to the weight of a vertical column of air extending upwards to the upper limit of the atmosphere per unit area. All barometers used in meteorology should be calibrated in hPa increments. Under standard conditions, a pressure of 760mmHg is equal to 1032.25hPa. Suitable for atmospheric pressure measurement in various environments. Adopting imported pressure sensors, the measurement is more accurate and reliable, with a beautiful and compact appearance, and easy installation.
