WIKA G 1/2 Analogue Pressure Gauge 250bar Bottom Entry, 9052330, 0bar min., 312.20

The WIKA model 312.20 mechanical test gauge has been specifically designed for the measurement of pressures with high accuracy. With its accuracy class of 0.6, the Bourdon tube pressure gauge is suitable for testing industrial type pressure gauges or for precision measurement in laboratories. For the respective measuring requirement, a scale range between 0 ... 0.6 and 0 ... 600 bar can be selected. The model 312.20 is constructed with a case from stainless steel and wetted parts from copper alloy. The optimal readability of the instrument, with a nominal size of 160 mm, is achieved via a knife edge pointer and a dial with fine divisions. Supported through the optional mirror band scale, the parallax error can be eliminated.
