Features and Benefits

  • View Multiple, Simultaneous Measurements:
    "Low Side", "High Side", and Temperature
  • Digital "Stub" Gauges:
    Minimize charge loss; perfect for "critical charge" applications
  • Minimized Mass Clamps:
    Compact stainless steel clamp for durability and easy placement
  • Thermally-Isolated Contact Sensor:
    Reduced thermal mass for greater accuracy
  • Advanced System Analysis:
    Superheat/Subcool Calculations, Reporting, and more with the ION HVAC/R App™

Wireless Gauge Features with the Appion Central App™

The Appion Central App™ enables remote, real-time viewing for appION™ Wireless Digital Gauges.

Multiple, simultaneous remote readings are now possible. Easy-to-use and perfect for advanced system analysis on evolving, complex, high-efficiency systems.

Access an extensive refrigerant P/T lookup and receive remote notifications from custom alarms when readings move beyond predetermined thresholds.

Active gauge readings enable superheat/subcool, real-time system analysis, custom layout configuration, multiple alarms, and more. More functionality, less bulk.
