Designed for measuring atmospheric pressure and absolute air pressure in the test volume at ambient air temperature from plus 5°C to plus 50°C and relative humidity up to 80%. The pressure measurement range is from 5 to 790 mmHg.
The barometer error tolerance limit when corrections are made is ±2.5 mmHg in the range from 5 to 100 mmHg and 1.5 mmHg in the rest of the range. The tightness of the barometer case ensures that the internal pressure does not change by more than 1.0 mmHg in 6 minutes at differences between the external atmospheric pressure and the limits of the measuring range. The barometer withstands 1000 cycles of pressure change at a rate of up to 25 mmHg per second from atmospheric pressure to 5 mmHg. Overall dimensions, mm, not more: diameter 205, height 125. Weight without case, kg, not more than 3.2. The barometer is a non-repairable product. The average service life of the barometer is not less than 6 years.
