Precision Test Gauges

Precision Test Gauges from Marsh Instruments are designed to provide reliable pressure measurements in harsh and corrosive sour gas environments.

The Marsh Test Gauge is designed with a black painted steel housing and the choice of copper alloy or 316 stainless steel tube and socket to meet the demanding service needs of various test gauge applications. Accuracy is ±0.5% of full span.

A highly polished integral mirror is positioned between the two graduation arcs on the dial face. The knife-edge pointer is reflective so that, when the pointer and its reflection are in alignment, parallax is virtually eliminated and a true dial reading is assured. Typical applications include test stands, aviation ground support petroleum, chemical, utilities, industrial vessels and panel builders.
