Violet Gauge Sidebar

R-134a SI Overview Chart — Violet Gauge Sidebar

A purple-rimmed pressure dial and small Celsius curve occupy the left sidebar beside a three-block table.

Start with the Celsius column to find an R-134a saturation temperature, then read across for the equivalent Fahrenheit temperature and pressure. Its 2°C spacing is useful when you want a broad metric reference on one sheet. This violet gauge sidebar version covers -40 to 80°C in 2°C steps.

The left sidebar combines a dial, a miniature saturation curve, and reference-state values; the larger table on the right supplies the listed lookup points. The 61 listed reference points use Celsius, Fahrenheit, bar gauge, kPa absolute.
