Matheson offers test gauges which are accurate to +/- 0.25% of full scale. Typically, these gauges are used to monitor critical process equipment within a facility.  For ease of reading, they are 6" in diameter with very precise and incremental measurement graduations and mirror scales.  Construction is Monel and operating temperature range is -20°F to 150°F (-30°C to 66°C).  All of the gauges offered by Matheson are constructed with the 1/4" MNPT inlet located on the bottom of the gauge and are cleaned for oxygen service.
