ION Pressure/Temperature Gauges

ION PT Gauges

High-Accuracy Pressure/Temperature Gauges
Digital Vacuum Gauge and High-Resolution Pressure Gauge also available

The ION PT Gauges are the latest in cutting edge technology from Appion. Developed after extensive field and laboratory testing, they are designed to be the optimal tool for technicians to use to precisely charge and diagnose AC/R systems. The ION PT Gauges are “stub” gauges designed to connect directly to systems, eliminating the need for hoses. This greatly reduces the risk of cross contamination, charge loss, and inaccurate measurements.

Digital "Stub" Gauges: No Hoses, No Manifold

Features and Benefits

  • View multiple, simultaneous measurements such as "Low Side", "High Side", and Temperature
  • Meets ASME / ANSI B40.7 Grade 2A standards
  • Every gauge is linked to an individualized downloadable 5-point NIST certificate for 3rd-party verification of accuracy
  • Digital "Stub" Gauges minimize charge loss and are perfect for "critical charge" applications
  • Minimized Mass Clamps made of compact stainless steel for durability and easy placement
  • Thermally-Isolated Contact Sensor reduces thermal mass for greater accuracy
  • Advanced System Analysis that includes Superheat/Subcool Calculations, Reporting, and more with the ION HVAC/R App™

With each ION PT Pressure Gauge accurate to +/- 0.5%, technicians can prove that their measurements will hold up to any audit nationwide. And every good technician knows that pressure is only half the battle, which is why each ION PT Gauge comes with a high accuracy minimized thermal mass temperature clamp. The ION PT Gauge clamp measures system temperature to within 0.27ºF. They are scientifically designed to minimize temperature variation by removing unnecessary clamp bulk while enabling technicians to attach the clamp where they need it most on any size pipe with the clamp's removable sensor.

Temp Sensor Group
The Bluetooth® enabled gauges give technicians multiple pressures and temperature measurements as well as advanced system analysis to use at their fingertips when paired with the free Appion ION HVAC/R™ App. The ION PT Gauges also have an LCD display giving real time pressure and temperature measurements so technicians are not dependent on their phone to successfully complete their job.
