Blue Gauge Console
R-134a SI Overview Chart — Blue Gauge Console
A pressure dial sits in a navy instrument frame, with light-blue accents linking the heading and Celsius columns.
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 blue gauge console version covers -40 to 80°C in 2°C steps.
The dark console border encloses the reference table, while the illustrated dial provides a visual cue for the pressure values. The 61 listed reference points use Celsius, Fahrenheit, bar gauge, kPa absolute.

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.
