What is read on a compound gauge?
What do compound gauges read? The diaphragm on a compound unit will measure vacuum pressure, which will read as a negative psi on a digital gauge, or often in inches of mercury (inHg) on an analog gauge. So 7.5 psi on an absolute pressure gauge would read -7.5 psi on a compound gauge at sea level.
What is compound gauge in refrigeration?
The compound gauges used for this, capable of measuring both vacuum and positive pressure, are called refrigeration gauges and utilize graduated dials with 270° displays and pressure range of either vacuum-150 PSI or vacuum-300 PSI.
