Fieldpiece Svg3 Micron Vacuum Gauge contains features to make evacuations simpler and faster.  The display has a vivid backlight for high visibility in any situation. To reduce leaks, the SVG3 has a Schrader depressor that can link directly to your core removal tool or immediately to the service port. Fewer links reduce the possibility of leaks unrelated to the system.  The rate indicator helps establish if there are any leaks within the system. When the vacuum reaches the low alarm setpoint, an audible alarm triggers, the backlight flashes, and the integrated stopwatch restart to show the specialist how long the system has kept at a deep vacuum.  You can set both high-level and low alarms.  And the timer can show how long it took to get to the alarm and how long the vacuum has been maintained.

Features of Fieldpiece Svg3 Micron Vacuum Gauge:

  • Rate Calculator- View how fast system pressure is rising or falling
  • Schrader Depressor- Minimizes leaks by reducing connections
  • In Fieldpiece it has 1 Micron Resolution, 0 – 9999 Micron Range
  • It has some Units of measure:  microns (µm) of mercury, mmHg, mbar, mTorr, Torr, and pascals
