GW Instek GDM-8145 - Instek (4 1/2 Digits) 4 1/2 Digits True RMS Digital Multimeter
4 1/2 (19999 Counts) LED Single Display.
In terms of cost/performance ratio, the GDM-8145 yields one of the best choices among the DMMs in today\'s market. It is equipped with 4 1/2 digits, and a 0.5 LED display in a distinctive red color. Measurement items include DC Voltage/Current, AC Voltage/Current with true RMS, Resistance and Diode Test. The true RMS AC and AC+DC response give accurate measurements for equivalent DC energy regardless of the waveform shape. Small voltage offsets are canceled by the auto-zero circuit, and protection mechanisms are available for the entire measurement range. All these features provide user with a robust measurement experience.
