For testing and calibrating the pressure source of general pressure gauges, supporting both positive pressure and vacuum verification.
Pressure Gauge Calibrator is a precision instrument designed for generating and verifying pressure sources of general pressure gauges.
It supports both positive pressure and vacuum calibration, with a maximum test pressure up to 70 MPa and a vacuum range down to –0.08 MPa, making it suitable for laboratories, calibration centers, and industrial inspection environments.
The pressure gauge calibrator is mainly used to test and calibrate the pressure source of common mechanical pressure gauges.
By using a stable pressure-generating mechanism and reliable sealing structure, it provides accurate pressure output and repeatable calibration results.
This calibrator supports pressure and vacuum testing, allowing users to verify gauge accuracy across a wide measurement range. Its compact structure, simple operation, and stable performance make it an ideal choice for routine pressure verification and quality control.
