Measures refrigerant pressure and temperature and calculates superheat or subcooling for R134A and R404A in English or metric units. Use the Fieldpiece ASX24 on refrigeration systems. Includes the Fieldpiece Instruments’ ATC1 Clamp Thermocouple that features a spring-loaded clamp to firmly hold the thermocouple junction up against a pipe, important when measuring line temperature.

After measuring suction line or liquid line temperature and pressure, the accessory heads calculate and display the actual superheat or subcooling, saving the technician the hassle of using charts to determine the numbers. Works with all of Fieldpiece’s modular instruments. Slide on to any of the HS30 series stick meters. The ASX14 and ASX24 heads can also be used with the data logger to record measurements over time. When used with the Fieldpiece Electronic Handle, EHDL1, the accessory heads become a standalone tool. They also connect to most DMMs using Fieldpiece's AHDL1 adapter handle.
