The brass wetted parts are for measuring non-corrosive liquid and gas\r\npressure. The black-painted steel case is Ingress Protection certified IP52\r\nfor protection against dust or liquids. The circular dial comes in 1.5\" (40\r\nmm), 2\" (50 mm), 2.5\" (63 mm), and 4\" (100 mm) diameters. The dial has an\r\naluminum black pointer. The lens for the 1.5\", 2\", and 2.5\"diameter dials is\r\npolycarbonate for high impact resistance. The lens for the 4\" diameter dial is\r\nglass for strength and clarity. The gauge measures pressure with a dual scale\r\nof either psi\/kPa or Hg. vacuum\/kPa. The gauge is accurate to + or - 3\/2\/3%\r\nover the entire range of the gauge, American Society of Mechanical Engineers\r\n(ASME) B40.100 Grade B accuracy class. The male connection is mounted on the\r\nbottom or center back of the gauge and has either a 1\/4\" NPT (National Pipe\r\nThread) or 1\/2\" NPT rate. The bourdon tube is phosphor bronze, the movement is\r\nbrass, and the welding is silver alloy. The over-pressure limit is 25% of full\r\nscale value. The working pressure is a maximum of 75% of full scale value. The\r\noperating temperature is -40 to 150 degrees F (-40 to 65 degrees C). This\r\npressure gauge is suitable for plumbing, heating, air conditioning, pneumatic,\r\nhydraulic, water tanks, and air compressors.Pressure gauges are instruments\r\nused to measure the pressure of a gas or liquid inside a vessel and, often, to\r\nhelp ensure the optimal amount of pressure for a given application. Pressure\r\ngauges can range from everyday instruments, such as those used to measure the\r\nair pressure in a car or bicycle tire, to highly accurate gauges used in\r\nmechanical and industrial processing. Most often, pressure gauges measure\r\npressure relative to another reference. For instance, gauge pressure measures\r\npressure relative to ambient air. An example of a pressure gauge measuring\r\nrelative to ambient air is a tire pressure gauge or a blood pressure gauge.\r\nDifferential pressure is the difference in pressure between two points, such\r\nas when measuring liquid flow along various points in a pipeline. An absolute\r\npressure gauge measures pressure relative to a perfect vacuum, such as an\r\natmospheric or barometric pressure gauge. All types of pressure gauges include\r\neither a male or a female mount to connect to the vessel where pressure is\r\nbeing measured, and display results on a dial with varying increments of\r\nmeasure across a given range.Winters Instruments manufactures pressure gauges,\r\nthermometers, diaphragm seals, pressure transmitters, and switches. The\r\ncompany, founded in 1953, is headquartered in Toronto, Canada.\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n  \u003cul class=\"a\"\u003e\r\n         \u003cli\u003eBrass wetted parts for measuring non-corrosive liquid and gas pressure\u003c\/li\u003e\r\n         \u003cli\u003eCircular dial is enclosed in a steel case for corrosion resistance\u003c\/li\u003e\r\n         \u003cli\u003eMeasures pressure with dual scale (psi\/kPa)\/(Hg. vacuum\/kPa)\u003c\/li\u003e\r\n         \u003cli\u003eDisplay accuracy is + or - 3\/2\/3% over the entire range of the gauge (ASME B40.100 Grade B)\u003c\/li\u003e\r\n         \u003cli\u003eLower mount or center back male connection with either 1\/8\" or 1\/4\" NPT rate\u003c\/li\u003e\r\n  \u003c\/ul\u003e","brand":"Winters Instruments","offers":[{"title":"Default Title","offer_id":44080069378228,"sku":"B0087UDFZM","price":155.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B0087UDFZM.jpg?v=1775776129","url":"https:\/\/auspowers.com\/products\/winters-4-inch-dial-size-multi-function-economy-utility-dry-pressure-gauge-brass-internals-steel-case-dual-scale-0-300-psi-kpa-3-2-3-accuracy-1-4-inch-npt-bottom-glass-lens-pressure-gauge-0-300-psi-kpa","provider":"AusPower Australia","version":"1.0","type":"link"}
