Pressure medium is diverse, such as water and air, as well as those with properties such as corrosive, flammable and toxic. If a pressure gauge is not applicable to these media, the gauge can not meet performance and even has a potential danger when used. Wet part materials can be hence selectable and special treatment to the part is accommodable.
| Category in use | Special Treatment | Indication | Applicable Pressure Medium | |
|---|---|---|---|---|
| Wet part material | ||||
| General | Cu-alloy | ― | ― | Non-corrosive liquids, gasses, water, oil and air, etc. |
| Steam/Heatproof | Cu-alloy,SUS | ― | Steam: M Heat-resistant: H (SUS-Ag) |
Vapor and 45 to 80C non-corrosive fluids or gasses (Cooling fin needed over 80C and discussion to determine specifications for remote diagram type required.) |

(1) Corrosive fluid: There is no material that can withstand all corrosive fluids. So, please let us know the name of fluid so that you can select the most suitable material.
(2) Acetylene gas: Usage of silver or copper alloy with copper content of 75% or more should be prohibited for wet part material. Thus, please be sure to contact us so that we can provide any appropriate solutions, accordingly.
