Product: HD780

Description: The HD780 Digital Manifold/Pressure Gauge is an all-in-one tool that lets HVAC pros measure suction-line or liquid-line pressure and line temperature to instantly obtain superheat and subcooling values. It also calculates differential pressure (P1-P2) and delta-T (T1-T2). The digital manifold is designed to withstand the demands of everyday use with a durable rubber holster design and a three-year warranty. The test instrument can be used with both R-22 and R-410a. Two ports are available for pressure readings and two inputs for temperature. The large, backlit display simultaneously indicates five readings: P1 or P2 along with a differential reading, T1 or T2 and differential temperature, and ambient temperature or data readings (minimum/maximum/average). One-touch data-hold freezes the display to capture important readings during testing.
