Digital Vacuum Gauges
The SuperEvac
™
LCD Vacuum Gauge is a portable, lightweight, solid
state instrument that indicates the vacuum pressure in the system
using thermocouple technology. This is important because you
need to know the vacuum to confirm moisture removal. The battery
powered gauge measures atmospheric pressures of 760,000 to 1
micron in easy to read 1/2” high numbers
(Part #69075)
