The rugged Extech EX570 is ideal for industrial/plant maintenance and electrical contractors. The affordable EX570 offers advanced multimeter functions, high accuracy (0.06%), True RMS precision plus an integrated infrared thermometer patented by Extech. The EX570 protects users with Category IV-600V and Category III-1000V safety ratings. The EX570 measures voltage, millivolt, current, resistance, capacitance, and frequency plus diode and continuity tests. Added functions include Min. /Max., Average, Hold, Relative, Peak Hold and “quick-note” memory for 3 readings. Thermocouple temperature readings are complemented by an infrared thermometer for safe, non-contact temperature measurement (30:1 distance to spot ratio). Built-in IR simplifies the identification of overheating motors, electrical panels, and other components from a distance and without a separate thermometer. Complete with double-molded test leads, temperature probe, magnetic hanging strap, 9V battery and case.
