Orange Thermometer Header
R-134a SI Overview Chart — Orange Thermometer Header
A yellow contact thermometer sits in a raised white panel within the orange heading, with Celsius-led columns underneath.
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 orange thermometer header version covers -40 to 80°C in 2°C steps.
The rounded heading leaves the reference table in its own white panel, separate from the equipment illustration. 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.
