ASX14 – Superheat & Subcooling

A/C Charging Kit.

Charge to Subcooling or Superheat.

Where to Buy

Recent studies suggest that the majority of A/C systems in operation in the U.S. are under or overcharged.  This causes decreased efficiency, and sometimes, premature compressor failure.  The Fieldpiece Superheat and Subcooling Accessory for Air Conditioning, model ASX14, measures suction line, or low side, line temperature and pressure.

It then calculates actual superheat in real time using built in P/T charts. It also measures liquid line, or high side, line temperature and pressure, and calculates actual subcooling.  Use it to get actual superheat on R-22 and R-410A fixed orifice systems and actual subcooling on TXV / TEV regulated systems.  Use the “T” fitting to charge to actual superheat or subcooling by putting the ASX14 in-line between your refrigerant bottle and the system.

Designed for HVACR professionals, the ASX14, measures refrigerant pressure and temperature, and calculates superheat for two refrigerants in English or metric units.

Specifications

  • Connector type: Standard 1/4” male flare fitting
  • Operating environment: 32ºF to 122ºF; 0ºC to 50ºC at <75%RH Allow ~5 min. for ASX14 to come to ambient temp
  • Storage environment: -4ºF to 140ºF; -20ºC to 60ºC at <80%RH with battery removed
  • Battery life: 25 hours typical. No measurable current draw when in “off” position
  • Low battery indication: Red LED lights
  • Battery: 9V
  • Auto off: Approx. 15 minutes
  • Overloads: The ASX14 outputs 3.4V when temperature or pressure is outside of their working range (overloaded). For ranges below 3400mVDC, the normal overload symbol will be displayed on the meter (“OL”). For ranges above 3400mVDC, reading displayed will be approximately 3.4VDC.
  • Stated Accuracy: at 73°F ± 9°F (23°C ±5°C) , <90% R.H
