EXTECH MG300 Multimeter

The Extech MG300 is a versatile multimeter featuring True RMS measurements for accurate readings of noisy, distorted, or non-sinusoidal waveforms. It offers 13 functions, including AC/DC voltage, current, resistance, capacitance, frequency, temperature, and diode/continuity testing. The device supports test voltages up to 1000V and insulation resistance measurements up to 4 GΩ. It includes duty cycle measurement and milliamps for 4-20mA current loops. The multimeter is equipped with a USB interface for real-time monitoring on a laptop or PC from up to 30 feet wirelessly, enabling convenient data recording. Additional features include auto discharge of capacitive voltage, a large backlit triple display, Min/Max and Relative modes, Data Hold, auto power off, and a waterproof (IP67) rugged design. It also has a lock power-on function for hands-free operation, and holds a CAT IV 600V safety rating.
