Ashcroft 593-20R Pressure Gauge

Ashcroft 593-20R is a 2-1/2-inch dial pressure gauge that delivers direct, local readings across a -30 to 30 psi range, enabling accurate monitoring of low-pressure or vacuum conditions in compact instrumentation where space is at a premium, and the sizable dial improves readability in crowded panels. The scale spans negative and positive pressures on a single face, so a single instrument can indicate both vacuum and pressure, reducing the number of gauges required for small-bore systems and simplifying instrument layouts in tight installations. The 593-20R designation places this device within Ashcroft's 593-series family of standard pressure gauges, a lineage known for straightforward interpretation and compatibility with common mounting practices in laboratories, workshops, and other environments where reliable, local pressure indication is essential.
