Monochrome Gauge and Curve

R-134a Pressure Lookup Chart — Monochrome Gauge and Curve

A grayscale pressure dial and rising curve sit above two blocks of pressure lookup values.

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 gauge and curve version covers 0 to 200 psig in 5-psi steps.

The small curve shows the overall pressure-temperature trend; use the table below it to read the listed values for individual reference points. 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.
