Monochrome Machined Dial
R-134a Pressure Lookup Chart — Monochrome Machined Dial
A silver dial and a thick gray beveled frame surround the two-section 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 monochrome machined dial version covers 0 to 200 psig in 5-psi steps.
The beveled border distinguishes the table from the heading, with alternating row shading helping you track a value across adjacent columns. 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.
