  • Sends live indoor wet bulb readings to the SMAN4 Digital Manifold while charging at the condenser.
  • Real-time Target Evaporator Exit Temperature and Target Delta T
  • Displays actual indoor unit performance and calculates how indoor unit should be performing.
  • Shows enthalpy change across the evaporator - in real-time.
  • Wirelessly sends all 4 evaporator temperatures to the HG3 System Analyzer for full system diagnostics

  • Hands-free testing
  • Bright backlight
  • Threaded probe locks
  • Ruled, 38" telescoping probes
  • Magnetic hanger
  • Rugged design
