CHY A830L Digital Multimeter – Handheld DMM with Backlight & Continuity Buzzer for Students

Overview

The CHY A830L is a compact, 3.5-digit digital multimeter designed for measuring DC and AC voltage, DC current, resistance, and performing diode and transistor tests. Its standout feature for students is the Continuity Buzzer, which provides an audible “beep” to check for broken wires or short circuits. Wrapped in a bright yellow protective “skin,” it’s designed to survive the bumps and drops of a busy classroom or lab environment.

Key Features

• Backlit LCD Display: Large, easy-to-read screen with a blue backlight—perfect for low-light troubleshooting.

• Manual Ranging: A great learning tool for students to understand voltage scales and measurement ranges.

• Data Hold Function: Freeze the reading on the screen so you can write it down in your lab report without rushing.

• Rugged Protection: Includes a removable thick rubber holster that provides shock resistance and a built-in kickstand.

• Transistor (hFE) Test: Built-in socket to check the gain of NPN and PNP transistors.
