The Extech HD780 is designed for use with R22 and R410A refrigerants. The HD780 concurrently measures suction line or liquid line pressure and line temperature to calculate and show superheat and sub cooling for A/C units. The Extech HD780 has dual inputs to measure differential pressure (P1-P2) and Type K temperature (T1-T2).
Included with the Extech HD780 are heavy duty connection hoses, Type K Temperature Clamp Probe and a bead wire Temperature Probe to satisfy a range of application standards.
