Features:
*Use our digital voltage gauge to accurately measure voltage, 2-line design, which is convenient for wiring and reverse connection protection.
*No external power supply -use measurement voltage as a power supply. Measurement range: DC4.5V-30V.
*Bright and clear LED display panel for easy reading. The automatic movement display is convenient.
*When there are a small amount of errors, the potentiometer on the circuit board is calibrated.
*High measurement accuracy, good stability, and convenient installation. Meet most application requirements.
*Low starting working voltage, red is as low as 4.5V, green is as low as 4.7V, blue is as low as 5.0V
