30 inches of Hg Vacuum Gauge | Terriss Industries

Mechanical Vacuum Gauge

0-30 inches of mercury mechanical vacuum gauge with a lazy hand with 1/4″ male NPT vacuum interface. The lazy hand will rest at the deepest vacuum reached so the operator doesn’t have to guess the deepest vacuum achieved.

30 in of Mercury Vacuum Gauge

  • (PN):  T-03-761
  • 0-30 inches of mercury
  •  1/4″ male NPT vacuum interface
  •  lazy hand

Please Note: All gauges are factory tested.  However, they must be checked on a dead weight tester prior to use.  Rough handling in shipment frequently causes gauges to go out of calibration.

DigiVac Recommendations
