Extech MM570A [MM570A-NIST] MultiMaster High-Accuracy Multimeter (DISCONTINUED SEE FLIR DM93-NIST)

True RMS Multimeter with 50,000/500,000 count LCD.
The Extech MM570A-NIST is a high accuracy full range multimeter functions with 0.02% basic DCV accuracy and up to 100kHz True RMS ACV bandwidth. Special True RMS combination AC+DC function for measurements of rectified AC (non-symmetrical) voltage and current waveforms. 4 to 20mA, displayed as 0-100% for process current measurements. Dual Type K Temperature inputs, Capacitance, Frequency, Resistance, Continuity, Duty cycle and Diode tests with. Max/Min recording with auto ranging, Auto Power off, Relative & Hold, as well as Peak function which captures transient pulses. Optional Windows compatible PC communication software and optically isolated cable. With NIST Calibration.
