Dead weight tester is mainly used to check 0.16, 0.25, 0.4 precision pressure gauges and as testing pressure gauge and pressure transmitter. It has the advantage of stability, repeatability, excellent accuracy. There are two cut-off valves at joints of measured instruments, it can close pressure between systems timely when the users need plus and reduce weights.
Ø Piston and cylinder is grinded precisely; small roundness error and clearance.
Ø Weights has been made correction of pressure deformation coefficient and local gravitational acceleration.
Ø Special piston pressure switch valve; piston pressure platform can be used as pressure pump or pressure source independently.
Ø Consistent with nominal range and measuring range.
Ø Can be equipped kg weights and Mpa weights.
Ø Using quick connectors, no leakage
Ø Nominal range/Measuring range:KD-0.25T(-0.1~0.25)MPa, KD-0.4T(0.1~0.4)MPa, KD-0.6T(-0.1~0.6) MPa

Please point out the accuracy you need.
PS: instrument is without gas supply, the user needs to order pressure pump and vacuum pump separately (2L/Sec.)
