Digital DC Null Detector – Advanced Replacement for Spot Reflecting Galvanometer
The Digital DC Null Detector is a modern, highly accurate instrument designed to replace the traditional spot reflecting galvanometer used in precision resistance measurement systems. It simplifies null detection during Kelvin Double Bridge operations by providing stable, digital micro-amp readings with exceptional resolution.
With its 4½-digit digital display, the instrument indicates the gradual decrease in current values from positive to negative as you balance the bridge. When the value reaches 00.00, the exact null point is achieved, ensuring precise and repeatable measurements.
The device functions as a high-sensitivity micro-amp meter, offering a maximum range of 199.99 µA and an impressive resolution of 0.01 µA, enabling highly accurate null detection even in demanding test environments. The front-panel Set Zero facility further enhances measurement accuracy.
Engineered with a vibration-proof design, it offers significantly better stability and performance compared to a spot reflecting galvanometer, making it the preferred choice for engineers and laboratories today. Durable, reliable, and easy to operate, the Digital DC Null Detector comes with a 1-year warranty, ensuring dependable long-term use.
