1000A AC/DC True RMS Clamp/DMM + IR Thermometer
This CAT IV True RMS clamp meter features a built-in IR thermometer with laser pointer for non-contact surface measurements from -58 to 518 °F (-50 to 270 °C). Clamp measures AC current up to 1000 Amp with a maximum resolution of 0.1 Amp. The 1.7-inch jaw fits around conductors up to 750MCM. Peak hold captures motor inrush currents and other surges. Data hold and auto power off functions. Other functions include AC/DC Voltage, resistance, Type K thermometer, capacitance and frequency. Complete with test leads, Type K temperature probe, 9 Volt battery and case.
