WIKA WIKA 232.50 / 233.50
WIKA Bourdon tube pressure gauge, all-stainless-steel case, for the process industry.
The WIKA 232.50/233.50 series is a Bourdon tube pressure gauge with a fully stainless steel case, intended for the process industry. Model 232.50 is the unfilled version, while 233.50 has a liquid-filled case, recommended where vibrations or pressure pulsations occur. The order code combines the model, the case size and the scale range, for example 232.50.100 or 233.50.160, where the last digits indicate case size NS 100 and NS 160 respectively.
For a quotation please send the full code from the label of the existing gauge or, if it is missing, the case size, the desired pressure range and the type of process connection. We bring in new pressure gauges to order, through EU supply channels, usually in 1–4 weeks. We do not confirm stock or price before checking the code in the manufacturer's documentation.

Frequently asked questions
What do we send for a quotation for the 232.50 or 233.50 pressure gauge?
The simplest is the full code from the label of the existing gauge, for example 232.50.100 or 233.50.160. If the label is no longer legible, the case size (NS 63, 100 or 160), the desired pressure range and the type of process connection, threaded or small flange, are sufficient.
What do we check before a quotation for the WIKA series?
We do not confirm availability from stock and we do not give prices in the series presentation; every time we check the full code in the manufacturer's current data sheet before sending a firm quotation, especially for pressure ranges close to the limits of the case.
Other WIKA series
We do not confirm from our own sources whether an older order code is still manufactured identically, but check every request against the manufacturer's current data sheet.
