Manometers are hydraulic cargo piston

Manometers — devices with measurement from 0,06 to 1000 MPas (Measure excessive pressure — a positive difference between absolute and barometric pressure)

Vacuum gages — devices the measuring discharges (pressure are lower than atmospheric) (to minus 100 kPa).

Manovakuummetra — the manometers measuring both superfluous (from 60 to 240000 kPa), and vakuummetrichesky (to minus 100 kPa) pressure.

Naporomera - manometers of small excessive pressures to 40 KPA

Draft gages - vacuum gages with a limit to minus 40 KPA

Tyagonaporomera - a manovakuummetra with the extreme limits which are not exceeding ±20 kPa

Data are provided according to GOST 2405-88

The majority of domestic and import manometers are manufactured according to the standard standards, in this regard manometers of various brands replace each other. At the choice of the manometer it is necessary to know: measurement limit, diameter of the case, device accuracy class. The arrangement and a carving of the union are also important. These data are identical to all let out in our country and Europe of devices.
