The NoShok 900 series stainless steel 304 case pressure gauge has brass wetted parts, a liquid-filled circular dial, a variety of connection types available, and measures pressure with a dual scale with an accuracy of + or - 1% or 1.5%. The brass wetted parts are for measuring non-corrosive liquid and gas pressure. The dial is 2.5" (63 mm) or 4" (100 mm) in diameter and enclosed in a stainless steel 304 case for corrosion resistance. The gauge has a safety relief disc on the top of the case. The lens for the 2.5" gauge is polycarbonate for high impact resistance. The lens for the 4" gauge is instrument glass for strength and clarity. The dial is filled with glycerin and water for protection against vibration and pulsation. The dial has a white aluminum background with black and red markings and is UV resistant. The 2.5" gauge has a molded plastic pointer. The 4" gauge has a balanced aluminum pointer with a black finish. The gauge measures pressure with a dual scale in psi/kPa, Hg. vacuum/kPa, bar/psi, or Hg. vacuum/bar. The 2.5" gauge is accurate to + or - 1.5% over the entire range of the gauge, American Society of Mechanical Engineers (ASME) B40.100 Grade A accuracy class. The 4" gauge is accurate to + or - 1% over the entire range of the gauge, ASME B40.100 Grade 1A accuracy class. The male connection is located on the bottom or center back of the gauge and is available with a 1/4" NPT (National Pipe Thread) rate, a 1/2" NPT rate, a 1/4" British Standard Pipe Parallel thread (BSPP) rate, or a 7/16" to 20" adjustable 1/8" rate. The movement is brass and nylon with highly polished bearing surfaces. The bourdon tube is phosphor bronze C-Type for gauges with up to 600 psi and a coiled safety tube for gauges above 600 psi. The gauge operates in fluctuating pressure up to 60% of the dial range and in static pressure up to 90% of the dial range. The ambient temperature for the gauge is -4 to 140 degrees F (-20 to 60 degrees C). The media temperature range is -4 to 140 degrees F (-20 to 60 degrees C). This pressure ga...
