The Triplett MM520-NIST is a 6000 count high performance digital multimeter with True-RMS readings to provide better accuracy when measuring non-sinusoidal or noisy waveforms. It offers a large variety of measurement features including AC/DC Voltage, AC/DC Current, AC/DC µA Current, Resistance, Temperature, Frequency, Capacitance, Continuity, and Diode Test. Additional features include Low Pass Filter (LPF) for filtering frequency and harmonic interference when measuring variable frequency drives, a built-in NCV Detector, data hold, relative mode, and 60A clamp adapter input can be used with virtually any clamp adapter that has a 10mV/A output. The rubberized overmolded housing provides impact and drop resistance in a sleek ergonomic design. ETL listed with CAT III 600V safety rating that provides superior resistance to damage from transient overvoltages in demanding settings. The MM520NIST is suited for a variety of industrial and residential applications such as security, home theater, electrical, HVAC installations and more.
