In addition to the indicated gauge pressure, what other information is presented on the compound gauge for the hypothetical refrigerant illustrated? Illustration GS-RA-16

Correct Answer: Option B — the saturation temperature of the refrigerant that corresponds to the gauge pressure at the point of measurement

Compound gauges display dual-scale graduations showing both negative/positive gauge pressures and the corresponding saturation temperature for the specific refrigerant, facilitating immediate subcooling and superheat analysis.
