Most non-electrical HVAC/R problems are charge related. Many systems in operation are undercharged or overcharged. This can cause decreased efficiency and compressor failure. The higher the efficiency of a system the more critical it is that it is charged properly

ATC1 included with all Superheat and subcooling heads

Features common to all Superheat & Subcooling Heads:

• Read temperature and pressure.

• ATC1 pipe clamp thermocouple included.

• STABLE LED indication.

• “T” refrigerant line connector included.

• Altittude compensation set.

• Auto off with disable option.

• T/C calibration.

For Superheat, the head measures suction line pressure and suction line temperature. It calculates actual superheat based on the refrigerant selected. Any of the three parameters can be displayed: pressure, temperature or superheat.

For Subcooling, the head measures liquid line pressure and liquid line temperature. It calculates actual subcooling based on the refrigerant selected. Any of the three parameters can be displayed: pressure, temperature or subcooling temperature.

Measures suction line pressure and temperatures and calculates superheat.

• Select R22 or R410A

Measures Suction line or Liquid line pressure and temperature to calculate and display superheat or subcooling for A/C.

• Select R22 or R410A

Measures suction line or liquid line pressure and temperature to calculate and display superheat or subcooling for refrigeration.

• Select R134A or R404A
