Vacuum gauges measure vacuum (negative pressure) by inches of mercury.We offer vacuum gauges which measure from -30 inHG to 0, 15, 30, 60, or 160 PSI. We also offer compound (or “boost”) gauges. Both our vacuum and compound gauges come in dial sizes from 1 ½” to 4” with center back or lower mounts (aka “bottom mounts"). They are available in both glycerin oil filled or dry utility versions.
The number after the V represents the positive range of a compound gauge.
For instance, products ending with V15 represents a pressure range of -30 inHG to 15 PSI.
