The COM-VM02 is a compact and high-precision digital DC voltmeter designed for accurate and detailed voltage measurement in low-voltage DC systems. With its 5-digit blue LED display, extremely fine resolution, and compact panel-mount design, it is ideal for laboratory, industrial, and educational use as well as integration into power supplies, battery systems, or electronic test equipment.

The voltmeter operates from a 3.5 – 30 V DC supply and measures voltages from 0 to 33 V DC with exceptional detail and accuracy. It offers an auto-scaling resolution of 0.0001 V (below 4.3 V) and 0.001 V (above 4.3 V), ensuring clear and stable readings across the full measuring range. With a measurement accuracy of ±0.03 % + 2 digits, the COM-VM02 delivers laboratory-grade precision in a compact, easy-to-use format.

The 0.36″ per-digit 5-segment blue LED display provides excellent readability even under bright ambient light, while the 500 ms refresh rate ensures smooth, real-time updates.

Installation is straightforward thanks to the four-wire connection system, which separates the measurement input from the power supply. The measurement ground and supply ground are internally connected, simplifying wiring and ensuring stable performance.

With a compact housing (48 × 29 × 22 mm), a lightweight design, and a wide operating temperature range (–10 °C to +65 °C), the COM-VM02 provides a reliable, precise, and space-saving solution for accurate DC voltage monitoring in professional and educational environments.
