The WIKA 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 WIKA 312.20 mechanical test gauge is constructed with a case from stainless steel and wetted parts from copper alloy. The instrument meets the requirements of the international industry standard EN 837-1 for Bourdon tube pressure gauges. 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.

The WIKA 614.11 and 634.11 capsule pressure gauges are based upon the proven capsule measuring system. The capsule measuring principle is particularly suitable for low pressures. On pressurisation, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated. The modular design enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges. Due to this high variance, regarding design and back mount connection, the instrument is suitable for panel mounting in a wide range of applications.
