Extech HD780 Data Sheet

HD780 Digital Manifold/

Pressure Gauge

Extech’s Heavy duty Digital Manifold/Pressure Gauge simultaneously measures suction line or liquid line pressure and line temperature to calculate and display superheat and sub cooling for A/C units. It also has dual inputs measuring differential pressure (P1-P2) and Type K temperature (T1-T2). For use with R22 and R410A refrigerants. Included are heavy duty connection hoses, Type K Temperature Clamp probe, and bead wire Temperature probe.
