Rare Vintage Pressure Differential Gauge Test Precision Vacuum. Device PPR-2M (device Petrova) Universal liquid manometer for calibration of differential-flow meters, vacuum meters, pressure gauges, gravitometers and other devices for measuring pressure or rarefaction. It allows to check the devices measuring the pressure in the range from 0 to 1000 mm of water. (if the working fluid is water) and from 0 to 1000 mm Hg. (if the working fluid is mercury) and measuring the rarefaction from 0 to 760 mm of water.
Pressure and vacuum are measured by the instrument in mm of water. For this, during the use of the device in the corresponding version, it is accordingly filled with either water or mercury.
At the same time, the device can work in one version, i. Either "on water" or "on mercury". Europe and Asia 10-30 days. United States and Canada 20-40 days. Australia and Brasilia 30-60 days.
