DESCRIPTION

Why Choose Gauges USE NO OIL ?

• EN 562, a European standard for gas pressure regulators and associated safety devices, includes specifications and requirements for components used in gas systems. one of the key considerations in gas systems is safety and preventing contamination of the gas supply. in this context, it's important to note that EN 562 recommends that pressure gauges used in gas systems should be oil-free or oil-resistant, and this recommendation is primarily driven by safety and contamination concerns. 

• These non-sparking dial gauges are used with welding regulators and manifolds. they are designed for safety when used on welding fuels or in proximity to welding equipment. gauges are compatible with many welding fuels and can be selected based on process connection size and location and pressure range.
