GW Instek GDM-8245 - Instek 50,000 Counts Dual Display Digital Multimeter
50000 Counts Dual Display Digital Multimeter
The GDM-8245 is an economical bench-top DMM equipped with a rich set of features. The GDM-8245 has similar functions to those of GDM-8246, but with slightly reduced DCV accuracy and no communication interface. The large 7 segment LED dual display features up to 50,000 counts and the ability to show two measurements at once: ACV plus frequency or dBm, DCV plus dBm or ACV ripple. The GDM-8245 carries an extensive list of measurement items - DC Voltage/Current, AC Voltage/Current with true RMS, Resistance, Capacitance, Frequency, Continuity (with beeper), Diode Test, and dBm. Additional measurement functions, such as Max/Min, Hold and Relative value. With great range, good accuracy and ability to accept up to 20A of current, the GDM-8245 is the perfect general purpose DMM.
