Absolute and gauge-pressure deadweight tester «MPA»

Complete replacement of deadweight testers type 2465, 2468, MPA15, MPAK, MAD-720, MAD-3M

Absolute and gauge-pressure measuring instruments calibration and verification: pressure calibrators, barometers, instrument pressure transducers (sensors), digital manometers, deadweight testers, with accuracy class of 0.008 and lower within the range from -0.1 to 10 MPa.

Advantages
Absolute and gauge-pressure measurement all-in-one instrument.

Modular system: to extend measurement range, several piston-cylinder assemblies (PCA) may be used within one basement with pressure generator.

High accuracy classes including secondary reference standards.

Modern system of instrument control and monitoring of all the units from one multitask touch screen.

Alternatively to analogues available, high accuracy measurement of residual pressure by precise membrane capacitive vacuum meter is provided.

Automatic start of PCA piston motor when the piston is in floating position.

Built-in pumps to create absolute and gauge-pressure up to 1 MPa.

Main device with reference piston-cylinder assembly (PCA) and set of weights
