Aneroid barometer M-67 (control)
Aneroid barometer M-67 (control). Designed to measure atmospheric pressure in ground conditions for indoor work at temperatures from -10 to +50 ° C and relative humidity up to 80%. The operating principle of the M-67 aneroid barometer is based on the property of membrane aneroid boxes to deform when atmospheric pressure changes. When the pressure changes, the linear movements of the membranes are converted by a transmission lever mechanism into angular movements of the indicating arrow above the scale. The process of measuring pressure with an aneroid barometer is extremely simple and does not require special skills. It is necessary to place the barometer in a horizontal position with the scale facing up. At the next stage, you need to eliminate friction in the mechanism of the device - to do this, you need to lightly tap your fingers on the body and glass. During the measurement process, when storing and transporting the barometer, you should avoid exposing the device to direct sunlight and moisture, and protect the device from sudden temperature fluctuations, shaking and accidental mechanical shocks. After the barometer has been at an air temperature below -10°C, before starting measurements, it is necessary for the device to stand at operating temperature for several hours. The M-67 barometer is a non-repairable product. Manba: https://www.nv-lab.ru/catalog_info.php?ID=4938
