Description
The Simpson 2123 panel meter is a versatile tool designed to measure both direct current (DC) and direct voltage (DCV). Housed in a classic black plastic case with a protective glass window for clear viewing, it features a rugged design for long-lasting performance. The 2123 comes in a variety of ranges, allowing you to select the perfect option for your application, whether you need to measure DC current up to 50 amps or DC voltage up to 200 volts. A clear scale and a precise black knife-edge pointer ensure accurate readings. UL recognized in some variations, the Simpson 2123 is a reliable choice for industrial settings or any application requiring measurement of DC current or voltage.
