The PIC Gauge HEX-108RN pressure gauge has brass wetted parts for measuring non-corrosive liquid and gas pressure, and a dry, non-fillable dial with a 1" diameter hex-shaped dial in a chrome-plated case that resists corrosion. The gauge measures pressure up to 1200 psi with 400 psi figure intervals and 80 psi graduation intervals, and is accurate to + or - 5% of span over the entire range of the gauge, or American Society for Mechanical Engineering (ASME) Grade D class. The center-back mount has a 1/8" National Pipe Thread (NPT) rate. This pressure gauge is suitable for use in severe application for measuring air, water, oil, gas, and other media not corrosive to brass.
