Wika 612.20 Low Pressure Capsule Pressure Gauge
Wika 612.20 Low Pressure Capsule Pressure Gauge
The WIKA® 612.20 low pressure gauge features a copper alloy capsule element that is designed to measure pressure and vacuum of gaseous media from as low as 2 1/2″ H2O to 275″ H2O (10 psi). The 4″ dial size allows easy reading from a distance. The finely polished nickel-silver pinion gear and shaft of the movement ensure repeatable accuracy.
