Violet Thermometer Ribbon
R-134a SI Overview Chart — Violet Thermometer Ribbon
A white thermometer panel overlaps the violet angled header, with purple rules separating the Celsius data below.
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 thermometer ribbon version covers -40 to 80°C in 2°C steps.
The angled header separates the illustration from the banded table, so the data remains grouped in a rectangular reading area. The 61 listed reference points use Celsius, Fahrenheit, bar gauge, kPa absolute.
Using this reference
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.
