1. Application Scenarios
Calibration of pressure sensors, transmitters, pressure gauges, etc.
Laboratory pressure reference transfer (compliant with ISO 17025).
High-precision pressure testing in industrial settings (such as the petroleum, chemical, and aerospace industries).
2. Common Types
Gas piston pressure gauges: Suitable for low pressures (from micro-pressures to several MPa), using air or nitrogen as the medium.
Liquid piston pressure gauges: Suitable for medium- and high-pressure ranges (up to 1 GPa), using hydraulic oil as the medium.
Portable/Benchtop: Choose based on the application scenario.
