Overview
The Simpson 1329 is a round analog panel meter from Simpson Electric’s Wide-Vue line, designed for reliable measurement of DC voltage and DC current in industrial systems. This model combines 0-50 DC millivolt and 0-1500 DC ampere measurement ranges on a single dial, making it suitable for both voltage monitoring and current measurement through external shunts. The meter features a self-shielding movement and is housed in a rugged high-density black plastic case with a clear glass window for easy readability.
