The Best Pirani Vacuum Gauge

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.

Digital Pirani Gauges and Indicators are recommended for the measurement of high vacuum in process applications with clear 4 Digit LED Display. The Pirani Gauge is ideal for applications in the rough to medium vacuum range. Applications include semiconductor manufacturing, vacuum pump suction, leak detection, vacuum coating, and freeze dryers.

The Pirani Gauge is ideal for applications in the rough to medium vacuum range. Applications include semiconductor manufacturing, vacuum pump suction, leak detection, vacuum coating, and freeze dryers. This Pirani Gauge instrument with two sensors having wide range of applications, in high vacuum systems where one sensor is used to measure backing vacuum and the other sensor can be used for measuring high vacuum. Pirani Gauge instruments can be used in high vacuum systems, coating units, sputtering units, and many other applications where vacuum to be measured in the range of 0.9 to 0.001 m.bar.
