Monel Gauge

The Monel gauge has been specifically designed to be used with aggressive process mediums that will attack 316 stainless steel. This was often manufactured with a diaphragm gauge, but in recent years a bourdon tube has been produced. This is a cost effective solution and has the same performance.
