DT830D Digital Multimeter DC/AC Voltage Current/A Resistance/ ohm Test
৳255
The DT830D is an entry-level digital multimeter widely used by students, hobbyists, and for light electronics work. It can measure DC and AC voltage, DC current, resistance, and also perform diode and transistor tests. The continuity function comes with an audible buzzer, making it easier to check circuits quickly.
It has a 3½‑digit LCD display (maximum reading of 1999), manual range selection, and is powered by a 9V battery. While not suitable for high-precision lab work, it provides reliable readings for everyday tasks, troubleshooting, and electronics learning projects.
