The AC5-1 DC Galvanometer (Model AC51) is a precision current detection instrument designed for laboratory measurements, industrial equipment monitoring, and precision instrument development. Utilizing an optimized magnetoelectric measurement principle, this device achieves accurate detection and analysis of micro DC currents, with a measurement range spanning from nanoamperes to milliamperes, meeting the demand for refined current monitoring in both scientific research and industrial applications.
Featuring a modular design, the main unit integrates sensitivity adjustment knobs and range switching devices, working in conjunction with an independently installed graduated display screen to ensure operational safety through physical isolation between the user and measurement system. The core sensing element employs specially formulated alloy materials combined with temperature compensation technology, maintaining stable measurement accuracy within ambient temperatures from -10°C to 50°C. A tri-axial anti-vibration bracket effectively minimizes environmental interference, complemented by a dual-layer electromagnetic shielding structure that guarantees reliable signal detection in complex electromagnetic environments.
This galvanometer supports bidirectional current detection, with both positive and negative currents clearly displayed through an analog dial indicator. The built-in overload protection mechanism automatically disconnects the measurement circuit during current surges to prevent equipment damage. Housed in a portable case with moisture-resistant and dust-proof layers, it adapts to diverse working environments including laboratories and mobile testing vehicles. Widely applied in precision instrument calibration, semiconductor material analysis, and medical device development, it provides dependable data support for new energy battery testing and industrial automation system debugging scenarios.
