Grayscale Vessel Landscape
R-134a Pressure Lookup Chart — Grayscale Vessel Landscape
A grayscale vessel labeled for vapor and liquid sits in the right sidebar beside the 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 grayscale vessel landscape version covers 0 to 200 psig in 5-psi steps.
The equipment and reference-state panel sits on the right, leaving the landscape table together on the left. 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.
