4-Port Wireless Digital Manifold with Micron Gauge

The SMAN460 wireless four-port digital manifold is the top-of-the-line Fieldpiece manifold. It has more features and benefits than any other manifold on the market. With target superheat automatically calculated, simultaneous superheat and subcooling, all 9 measurements displayed on the large, easy-to-read screen, extra large 3/8' full bore and 4th VAC port, and wireless measurements for real-time system diagnosis and charging, the SMAN460 is the manifold HVACR pros trust to do more.

Plus it has a built in micron vacuum gauge with gives technicians the ability to set high and low alarms, and a stopwatch, as well as view the micron rate of change.

  • Wireless Advantage
    • Receive indoor wet bulb and outdoor dry bulb measurements for live target superheat (additional instruments required).
    • Send measurements to Fieldpiece wireless system analyzers for diagnostics, data storage, and reporting.
  • Micron Alarms and Stopwatch
    • Set high and low alarms (microns of mercury).
    • Activate low alarm when you start pulling down. The stopwatch will start. When your low alarm sounds, the stopwatch will restart.
    • Activate high alarm when you isolate the system and the stopwatch resets again. When the system rises to your high alarm, the stopwatch will freeze.
    • Watch rate of change while pulling vacuum.
  • 4 Ports for One Time Hookup
    • Connect to high side, low side, vacuum pump, micron gauge, and recovery machine (or refrigerant tank). Then use the valves as needed to recover, evacuate and charge the system.
  • 3/8” Vacuum Port
    • The large 3/8” vacuum port and 3/8” full bore speeds up evacuation and charging.
  • Display Designed for HVACR
    • Huge screen with the information you need.
    • No more cycling through temperatures.
    • Calculated and measured values all shown.
    • Expanded temperature tolerances allow for testing in refrigerators and on rooftops.
    • Rugged polycarbonate LCD cover.
    • Bright backlight.
  • Temperature Solutions
    • Pipe clamps grip tight for speed and accuracy.
    • External cal. pots for easy field calibration.
  • Reliable Regardless of Elevation
    • Absolute pressure sensors give you accurate readings at any elevation.
  • Lab Quality 2-Point Field Calibration
    • Calibrate pressure sensors to the known pressure of your refrigerant tank at a known temperature for high accuracy over the entire pressure range.
  • And More
