Air condition pressure gauge for refrigerant R744

The air condition pressure gauge for refrigerant R744 is a professional-grade instrument designed for precise measurement of both high and low pressure in automotive and industrial air conditioning systems using R744 (carbon dioxide) refrigerant.

It includes high- and low-pressure hoses and a connection hose for integration with service devices. The central valve block is equipped with shut-off valves in piston design, allowing safe and controlled measurement. The system is enhanced with a retaining hook for easy suspension during diagnostics.

The pressure gauges, each 70mm in diameter, are shock-protected for added durability. Measurement ranges and resolutions are as follows:

• Low-pressure gauge:

  • 0–1425 PSI (resolution: 25 PSI)

  • 0–10 MPa (resolution: 0.1 MPa)

• High-pressure gauge:

  • 0–2250 PSI (resolution: 50 PSI)

  • 0–16 MPa (resolution: 0.2 MPa)

This gauge is an ideal replacement for damaged pressure gauges on existing service units, but it can also be used independently for diagnostic purposes without a service device.
