SVG3 – Digital Micron Vacuum Gauge

Simply rugged.

Where to Buy

Schrader depressor to minimize leaks by reducing connections
Rate calculator to indicate how fast pressure is rising or falling
Micron, mmHg, mbar, mTorr ,Torr, Pascals
Alarms and stopwatch
Units of measure: microns (µm) of mercury, mmHg, mbar, mTorr, Torr, and Pascals

The SVG3 Digitial Micron Vacuum Gauge is a compact, rugged gauge that is loaded with features HVACR professionals need to help them do more.  It includes a large, dual display with a rate indicator, alarms, timer, rugged rubberized case, and a hook at strap that allows the vacuum gauge to be hung at any angle.

The SVG3 contains features to make evacuations easier and faster.  The display has a bright backlight for high visibility in any situation. To minimize leaks the SVG3 has a schrader depressor that can connect directly to your core removal tool, or directly to the service port. Fewer connections reduce the potential for leaks unrelated to the system.  The rate indicator helps determine if there are any leaks within the system.

When the vacuum reaches the low alarm set point, an audible alarm triggers, the backlight flashes, and the integrated stopwatch restarts to show the technician how long the system has maintained a deep vacuum.  You can set both high and low alarms.  And the timer can display how long it took to get to the alarm and how long the vacuum has been maintained.

Specifications

  • Operating temperature: 32°F (0°C) to 122°F (50°C) at <75%RH
  • Storage temperature: -4°F to 140°F (-20°C to 60°C), 0 to 80% RH (with battery removed)
  • Temperature coefficient: 0.1 x (specified accuracy)/°C (<18°C or >28°C)
  • Over range: “OL” is displayed
  • Power: 4 x AAA batteries, NEDA 24A, JIS UM4, IEC R03
  • Auto power off: after 15 minutes of readings more than 10,000 microns if APO is active
  • Battery life: 40 hours standard use (alkaline) without backlight use
  • Low battery indication: is displayed when the battery voltage drops below the operating level
  • Units of measure: microns (µm) of mercury, mmHg, mbar, mTorr, Torr, and Pascals
  • Connector type: Standard 1/4″ female flare fitting. “T” fitting included ( 3 male flare ports)
  • Range: 0 to 9999 microns of mercury (9.999 mmHg, 13.33 mbar, 9999 mTorr, 9.999 Torr, 1333 Pa)
  • Accuracy: ±(5% of reading + 5 microns), 50 to 1000
  • Resolution: 1 micron (50 to 2000 microns), 250 microns (2001 to 5000 microns), 500 microns (5001 to 8000 microns), 1000 microns (8001 to 9999 microns)
  • Rate: Units selected per minute
  • Refresh rate: 0.5 seconds
  • Atmospheric pressure: “OL” will be displayed
  • Maximum overload pressure: 500 psig
  • Why does my SVG3 read o/l or my SVG3 is leaking as it only shows OL?

    • The micron gauges will not show any value higher than 9999 microns.

      Quick check- connect SVG3 to vacuum pump directly using a ball valve- ball valve is used in case oil gets back from pump and contaminate sensor

  • Why do my microns jump up when I turn off my vacuum pump?

    • The moisture inside the system is still boiling off and is no longer being taken out or compensated for by the vacuum pump.

      System will have to come to an equilibrium/ stabilizing.

  • How do I check if SVG3 is leaking or not?

    • Connect SVG3 to empty recovery pump and pull down to 500 microns and isolate the pump from recovery tank and microns should rise slowly not immediately /fast rise.

  • Why will my SVG3 show microns when directly hooked up to pump but not when I am pulling on a system?

      1. Leak is somewhere in the system connection
        1. Check all hoses for possible leaks
      2. Moisture is present in the system and it will take some time
      3. Perform triple evacuation on system
      4. Change the oil in the vacuum pump
  • How to clean/ maintain SVG3?

    • Clean the sensor of the SVG3 with rubbing alcohol.  Check manual for details.

  • Where is the serial number located on the SVG3?

    • The serial number is located on the back of the SVG3 under the strap.

  • Where is the best location to put the SVG3 for most accurate micron reading?

    • Connect to system. Techs typically prefer connecting to the Schrader Core Removal Tool (SCRT) or an unused service port.
