Deadweight tester «MP»

The device is available in nine versions: 6, 60, 100, 250, 400, 600, 1000, 1600, 2500 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, deadweight testers of accuracy class 0,008 and lower in range from 0,04 to 250 MPa.

Advantages
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.

Set of weights made of stainless steel (stainless non-magnetic steel for instruments of accuracy class 0,01 and 0,005).

Working fluid for all models — transformer fluid. Hydraulic system for pressure generating includes pre-filling pump and screw press.

Piston-cylinder assemblies (PCA) for MP 60 and MP 600 can be manufactured suitable for using with one and the same set of weights.
