Refrigeration Gauge

The Refrigeration Gauge from Marsh Instruments is sturdily constructed and tested to give long, continuous, accurate service. In addition to the standard pressure or compound scale, dials also show the corresponding temperature scales for R-12, R-22, and R-502, in the various combinations shown in the chart below. Dial markings are sharp, clear and easy to read.

Marsh Instruments Refrigeration Gauges are designed specifically for use on refrigeration systems.
