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 [6,000 psi].

For the respective measuring requirement, a scale range between 0 … 0.6 and 0 … 1,600 bar [0 … 10 psi and 0 … 20,000 psi] can be selected.

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 scale can be chosen to avoid the parallax error.

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.

On request, a calibration certificate will be provided for this instrument.
Safe storage and transport is ensured by a transport case (accessory).
