Wika 632.50, 633.50 Low Pressure Capsule Pressure Gauge
Wika 632.50, 633.50 Low Pressure Capsule Pressure Gauge
The WIKA® 632.50 and 633.50 low pressure gauges offer the corrosion resistance of 316 SS wetted parts, and are able to measure pressure and vacuum of gaseous media from as low as 1″ H2O to 275″ H2O (10 psi). The finely polished nickel-silver pinion gear and shaft of the movement ensure repeatable accuracy.
