SKU# 45335OX
Standard Oxygen Process Gauge, 4,000 psi - A 2.5" dial gauge with a pressed-brass case and a 1/4" NPTM bottom stem mount. 2% accuracy. For general oxygen pressure monitoring. Additional Info: Preparation of diving gas mixtures requires the use of special gauges which are more precise than normal process gauges. Nitrox / Trimix certification agencies all agree that instruments with 0.25% accuracy (1/4 of 1%) must be used to routinely get correct mixtures. GMC offers several mixing gauges with test-gauge accuracy as well as oxy-clean process gauges (1-3 % accuracy) for general applications. All models delivered oxy-clean.
