In terms of cost/performance ratio, the GDM-8135 yields one of the best choices among the DMMs in today's market. It is equipped with 3 1/2 digits, 0.5" LED display in a distinctive red color. Measurement items include DC Voltage/Current, AC Voltage/Current, Resistance, Diode Test, and Continuity with Beeper.

Small voltage offsets are canceled by the auto-zero circuit, and protection mechanism is available for the entire measurement range. All these features provide users with robust measurement experience.

Features:

Vast Measuring Functions : AC/DC Voltage, AC/DC Current, Resistance, Diode Test and Continuity Beeper
Large 0.5" Red LED Display
High Voltage 1000V and 20A Current Range
All Range with Protection Circuit
0.1% DCV Accuracy
Auto Zero Circuit
