Product Introduction

All specifications comply with the metrological inspection regulation.

● Pistons and piston cylinders are precision ground, resulting in minimal roundness error and clearance. This significantly enhances the piston's rotational longevity, thereby reducing the piston's descent speed and improving its discrimination ability.

● Weights have been corrected for pressure deformation coefficient and local gravity acceleration.

● Specifically designed pressure converting valve, which can operate independently without weights when closed; the piston pressure gauge platform can be used as a pressure pump or source individually.

● Measurement Range: Nominal Measurement Range Consistent with Actual Measurement Range

● Suitable for transmitting use as a piston-type pressure gauge; also for high-precision testing. Comes with kg weights and MPa weights.

● Simultaneously inspect two gauges, using quick pressure connectors, with no leakage observed.
