How It Works

Reading a Refrigerant Gauge

STEP 01 · CONNECT

Connect to Service Port

Attach to the suction (low side, blue) or discharge (high side, red) service port using a 1/4" SAE flare connector or specified fitting.

STEP 02 · PRESSURE

Read the Pressure Scale

The outer dial ring shows system pressure in MPa, bar or psi directly from the Bourdon tube pointer deflection.

STEP 03 · TEMPERATURE

Check Saturation Temperature

The inner colour ring shows the corresponding refrigerant saturation temperature — diagnose superheat and subcooling instantly.

Buyer FAQ

Frequently Asked Questions

What refrigerants are your gauges compatible with?

We supply gauges scaled for R410A, R22, R134a, R404A, R32, R507A and others. Specify the refrigerant at RFQ stage for correct scale and material selection.

What does the inner scale on the dial mean?

The inner colour ring shows the saturation temperature corresponding to the reading pressure for the specified refrigerant — no conversion chart needed during service.

Can I get matched high-side and low-side gauge pairs?

Yes. Matched low-side (blue) and high-side (red) pairs are available for manifold sets. Specify at RFQ stage and we'll match scales and cases.

What connection types are available?

SAE 1/4" flare, NPT and BSP. SAE flare is standard for HVAC service equipment. Confirm the thread standard used in your market when ordering.

Can you print our brand logo on the dial?

Yes. Custom dial printing with your logo, brand name, colour scheme and refrigerant scale is available. Minimum quantities apply — confirm via RFQ.

Are samples available before bulk order?

Yes. Evaluation samples can be arranged. Note your sample requirement when submitting the RFQ and we'll confirm availability and cost.
