Extech EX840 1000A AC/DC True RMS Clamp/DMM + IR Thermometer
1000A AC/DC True RMS Clamp/DMM + IR Thermometer

This CAT IV True RMS clamp meter includes an integrated IR thermometer with laser pointer for non-contact surface measurements ranging from -58 to 518 °F (-50 to 270 °C). Clamp measures alternating current up to 1000 amps with a maximum resolution of 0.1 amp. The 1.7-inch jaw accommodates conductors up to 750MCM. Peak hold measures motor inrush currents and other surges. Functions for data storage and automatic power off. Other features include AC/DC voltage, resistance, Type K thermometer, capacitance, and frequency. The kit includes test leads, a Type K temperature probe, a 9-volt battery, and a casing.
