Fieldpiece ASX14 Superheat and Subcooling Accessory Head for Air Conditioning

Recent studies suggest that over half of the AC systems in operation in the U.S. are undercharged or overcharged. This causes decreased efficiency, and sometimes, premature compressor failure. The Fieldpiece Superheat and Sub cooling 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 sub cooling. Use it to get actual superheat on R-22 and R-410A fixed orifice systems and actual sub cooling on TXV / TEV regulated systems. Use the T fitting to charge to actual superheat or sub cooling by putting the ASX14 in-line between your refrigerant bottle and the system.
