332.50 WIKA precision test gauge with bourdon tube

Description

The 332.50 WIKA precision test gauge with Bourdon tube is used for precision pressure measurement of gaseous and liquid media.

The Model 332.50 high quality gauge has been specially designed for measuring pressures with high accuracy. The Bourdon tube pressure gauge with its accuracy class 0.6 is suitable for testing industrial-type pressure gauges or for precision measurement in laboratories. Optional accuracy class 0.25 is available for pressures ≤ 400 bar.

For each measurement requirement, you can select a scale range between 0 … 0.6 and 0 … 1600 bar.

Optimum readability of the instrument with a nominal size of 160 mm is achieved by a knife-edge pointer and a dial with fine dividers. The parallax error supported by the optional mirror-band scale can be corrected.

Precise movement, wear-resistant, wetted parts and housing made of high-quality stainless steel. The instrument complies with the requirements of the international industry standard EN 837-1 for Bourdon pressure gauges and has an exhaust device on the back of the housing. In the event of a failure, overpressure can leak in and the operator is protected at the front. In severe operating conditions (e.g. vibration), instruments are also available with an additional liquid refill.

You can create an optional DKD/DAkkS calibration certificate for this instrument.
A transport case (accessory) ensures safe storage and transport.
