产品介绍：

Common pressure meter series are suitable for measuring the pressure of liquid, gas and steam or vacuum, which are non-crystalloid and non-concretionary, and have no danger of explosion and do not erode steel and copper alloy.

The meter is composed of pressure leading system (including joint, spring tube, etc), gear wheel driving machine, indicator device (pointer and meter dial) and crust (including meter crust, meter cover, meter glass, etc).

Under the action of pressure and vacuum, spring tube will produce elastic deformation causing displacement at the end. The displacement is enlarged by mechanical driving device and transferred to indicator, and then the pointer of the meter dial, with measure unit on it, indicates the pressure value or vacuum value
