Gas pressure balance   «MGP»

The devise is available in ten versions: V, 0.2, 0.5, 1, 2.5, 4, 10, 25, 100, 160 with accuracy class from 0,005 to 0,05

The device is designed for calibrating gauge pressure measuring instruments: pressure calibrators, pressure transducers (sensors), reference and other manometers, pressure balances of accuracy class 0,008 and lower in range from −0,003 to 16 MPa.

Advantages
Integrated source of test pressure generating in range −0,095…1 MPa (except for MPG 100). Working medium — air or nitrogen.

Piston-cylinder assembly (PCA) made of tungsten carbide provides for significantly reduced (fourfold) temperature effect on measurement results, long-term stability, wear resistance and durability of the device.

The device can be equipped with several PCA to allow for measurement range extension.

MGP 100 and MGP 10 with weights manufactured for
local value of gravitational acceleration
