The model 33x.50 high-quality 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. Optionally, an accuracy class of 0.25 is available for pressures ≤ 400 bar.

For the respective measuring requirement, a scale range between 0 ... 0.6 and 0 ... 1,600 bar can be selected.

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 wear-resistant precision movement, the wetted parts and the case are made from high-grade stainless steel. The instrument meets the requirements of the international industry standard EN 837-1 for Bourdon tube pressure gauges and has a blow-out device with blow-out plug on the back of the case. In the event of a failure, overpressure can escape there and the operator is protected at the front side. For harsh operating conditions (e.g. vibrations), the instruments are also available with an optional liquid filling.

For this instrument, an optional DKD/DAkkS calibration certificate can be generated.
Safe storage and transport is ensured by a transport case (accessory).
