Aneroid barometer BAMM-1 (meteorological)
METEOROLOGICAL ANEROID BAROMETER BAMM-1 Atmospheric pressure measurement range from 80 to 106 kPa (600 to 800 mmHg) Limits of permissible measurement error, no more main: ±0.2 kPa (1.5 mmHg); additional: ±0.5 kPa (3.75 mmHg) Graduation value: 0.1 kPa (scale in mmHg is available on request, division price: 1.0 mmHg) Aneroid meteorological barometer BAMM-1 is included in the register of measuring instruments of the Russian Federation (certificate No. 15434, State Register No. 5738-76) Barometer - aneroid meteorological BAMM-1 is designed for measuring atmospheric pressure in ground conditions at temperatures from 0 to plus 40 ° C and relative humidity up to 80%. The operating position of the device is horizontal, scale up Procedure for measuring atmospheric pressure: it is necessary to eliminate friction in the moving joints of the mechanism by lightly striking the body or glass of the barometer with your fingers; to avoid distortions during reading, the viewing angle must be perpendicular to the plane of the scale; counting is carried out with an accuracy of 0.05 kPa (0.5 scale division); the barometer reading must be corrected by introducing a temperature correction and a scale correction into its readings (the calculation of the corrections is given in the barometer passport) At least once every 12 months, it is necessary to recertify the barometer in the divisions of verification organizations Barometer dimensions: diameter 152 mm, height 90 mm Device weight no more than 0.7 kg Each barometer has its own individual serial number written on the display Manufacturer: JSC Safonovsky Plant Gidrometpribor Warranty period: 12 months Transportation by air is prohibited Delivery set: barometer, passport with initial verification mark Manba: https://www.nv-lab.ru/catalog_info.php?ID=1303
