Description
The Winters PEM series pressure gauge with brass wetted parts has a circular dial enclosed in a steel case and a male connection, and measures pressure with a dual scale (psi/kPa)/(Hg. vacuum/kPa) with an accuracy of + or – 3/2/3%. The brass wetted parts are for measuring non-corrosive liquid and gas pressure. The black-painted steel case is Ingress Protection certified IP52 for protection against dust or liquids. The circular dial comes in 1.5″ (40 mm), 2″ (50 mm), 2.5″ (63 mm), and 4″ (100 mm) diameters. The dial has an aluminum black pointer. The lens for the 1.5″, 2″, and 2.5″diameter dials is polycarbonate for high impact resistance. The lens for the 4″ diameter dial is glass for strength and clarity. The gauge measures pressure with a dual scale of either psi/kPa or Hg. vacuum/kPa. The gauge is accurate to + or – 3/2/3% over the entire range of the gauge, American Society of Mechanical Engineers (ASME) B40.100 Grade B accuracy class. The male connection is mounted on the bottom or center back of the gauge and has either a 1/4″ NPT (National Pipe Thread) or 1/2″ NPT rate. The bourdon tube is phosphor bronze, the movement is brass, and the welding is silver alloy. The over-pressure limit is 25% of full scale value. The working pressure is a maximum of 75% of full scale value. The operating temperature is -40 to 150 degrees F (-40 to 65 degrees C). This pressure gauge is suitable for plumbing, heating, air conditioning, pneumatic, hydraulic, water tanks, and air compressors.
Pressure gauges are instruments used to measure the pressure of a gas or liquid inside a vessel and, often, to help ensure the optimal amount of pressure for a given application. Pressure gauges can range from everyday instruments, such as those used to measure the air pressure in a car or bicycle tire, to highly accurate gauges used in mechanical and industrial processing. Most often, pressure gauges measure pressure relative to another reference. For instance, gauge pressure measures pressure relative to ambient air. An example of a pressure gauge measuring relative to ambient air is a tire pressure gauge or a blood pressure gauge. Differential pressure is the difference in pressure between two points, such as when measuring liquid flow along various points in a pipeline. An absolute pressure gauge measures pressure relative to a perfect vacuum, such as an atmospheric or barometric pressure gauge. All types of pressure gauges include either a male or a female mount to connect to the vessel where pressure is being measured, and display results on a dial with varying increments of measure across a given range.
Winters Instruments manufactures pressure gauges, thermometers, diaphragm seals, pressure transmitters, and switches. The company, founded in 1953, is headquartered in Toronto, Canada.

Description
Robinair proudly introduces the RAVG-1; one of the most sophisticated Digital Micron (vacuum) Gauges available for field service. Packaged in the same convenient case as our successful Digital Pressure gauges, this standalone gauge is compact and can be used anywhere. The RAVG-1 employs a sophisticated MEMS Pirani type sensor that directly measures flow. Unlike all other field service gauges on the market, the RAVG-1 is not affected by temperature. The RAVG-1 measures vacuum from atmosphere to 10 microns in 6 different scales, and can withstand overpressure beyond 30 bar. The unit employs an industry first multi-color backlight that functions as an instant go/no go indicator of acceptable vacuum or leakage. The product is not designed to read zero when initially powered on. Once the gauge is ready to use it will display a nominal indication of atmospheric pressure, as well as the enunciator ATM. These values are simply indications of atmospheric pressure to show that the gauge is not detecting a vacuum. The product should not be used as a measure of true atmospheric pressure. The product can display vacuum in one of 6 different units of measure: Microns (of Mercury), Inches of Mercury (inHg), Millibars (mBar), Millimeters of Mercury (mmHg), Pascals (Pa), or Torr. To change the units of measure; press the UNITS button on the lower left of the gauge front. Each time the button is pressed the unit of measure is changed. The selected unit of measure is indicated by the enunciator along the bottom of the display. The product will start up in the scale it was in when it was powered off. The factory setting is Microns. Robinair, a Bosch Automotive Service Solutions brand, is a global leader in service tools and equipment based in Owatonna, Minnesota. Robinair is recognized throughout the world as the quality and performance leader in AC/R evacuation tools and this position has led to its success with the full range of products that serve the heating/ventilating/air conditioning/refrigeration (HVAC-R) and mobile markets, which includes the automotive aftermarket along with other industries such as agriculture and construction.
