The General Electric 250-2-1/2 Panel Meter is a versatile and reliable instrument designed for measuring and displaying direct current (DC) and alternating current (AC) electrical quantities, specifically milliamperes (mA) within the range of 0-100 mA. This meter is an essential component for various industrial and laboratory applications, providing valuable insights into electrical systems.
The meter's rugged construction is a testament to its durability and ability to withstand harsh environments. It features a 2 1/2-inch (63.5 mm) dial face, which is large enough to offer clear and easy-to-read indications. The dial face is divided into two scales: one for DC current and the other for AC current. Each scale is calibrated to accurately measure and display current values within the specified range.
The meter employs a high-quality, moving coil mechanism to convert electrical current into mechanical motion, which in turn, drives the dial to indicate the current value. The meter's high-precision internal components ensure accurate and consistent readings, even under varying load conditions.
The General Electric 250-2-1/2 Panel Meter comes with a variety of mounting options, including surface, flush, and panel mounting, to accommodate different installation requirements. It also includes a shunt for low current applications, allowing users to measure extremely small currents with high accuracy.
Additionally, this meter features a robust construction with an IP20 rating, which ensures protection against dust and accidental contact with water. The meter's front bezel is made of impact-resistant material, further enhancing its durability.
The General Electric 250-2-1/2 Panel Meter is an excellent choice for anyone seeking a reliable and accurate milliamperes measuring instrument for their electrical systems. Its combination of rugged construction, versatile mounting options, and high-precision measurement capabilities make it an indispensable tool for industrial, laboratory, and educational applications.
