Description
The model 312.20 mechanical test gauge has been specifically designed for the measurement of pressures with high accuracy. With its high accuracy, 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 bar and 0 ... 600 bar [0 ... 10 psi and 0 ... 10,000 psi] can be selected.
The model 312.20 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 [6"], is achieved via a knife edge pointer and a dial with fine divisions. In addition, a mirror band scale can be chosen to avoid the parallax error.
On request, a calibration certificate will be provided for this instrument.
Safe storage and transport is ensured by a transport case (accessory).
