Charcoal Gauge Console

R-134a Pressure Lookup Chart — Charcoal Gauge Console

A grayscale dial and slim gray stripe head a charcoal console around the two-block pressure lookup table.

This version starts with gauge pressure rather than temperature. Find a listed psig value, then read across for the matching R-134a saturation temperature in Fahrenheit and Celsius; the 5-psi spacing makes the pressure steps easy to follow. This charcoal gauge console version covers 0 to 200 psig in 5-psi steps.

The dark console border encloses the reference table, while the illustrated dial provides a visual cue for the pressure values. The 41 listed reference points use psi gauge, Fahrenheit, Celsius.

The PDF preserves the one-page print layout. The matching Image is a full-resolution WebP rendering. These are finished reference sheets with fixed data and illustrations.

Gauge pressure uses a 101.325 kPa atmospheric reference. Saturation values describe the refrigerant relationship; equipment instructions determine operating and charging targets.
