The EX810-NISTL Clamp meter features a built-in IR thermometer with laser pointer for non-contact surface measurements from -58 to 518 degrees Fahrenheit (-50 to 270 degrees Celsius). Clamp measures AC current up to 1000 Amp with a maximum resolution of 0.1 Amp. The 1.7 in. jaw fits around conductors up to 750MCM. Peak hold captures motor inrush currents and other surges. Data hold and auto power off functions. Other features include AC/DC voltage, resistance, capacitance and frequency. Complete with test leads, 9 Volt battery and case. Includes a limited NIST traceable certificate.
