Welding pressure gauges 404 are produced in compliance with EN562 standard. Mainly used for simple pressure measurements of industrial gases, that require oxygen purity, that do not have corrosive effect on copper alloys and their viscosity allows for use of measurement mechanism with bourdon pen.

Welding pressure gauges are suitable for measurements of industrial gases (acetylene, oxygen). Supplied in industrial gases design or universal design (NEUTRAL).

Environment temperature -40 up to 60°C, maximum medium temperature Tmax 60°C. Other design options on individual request special scale design, connection threads, etc.
