Galvanometer Zero Center Analogue China.

Designed as a center‑zero analog galvanometer, it measures current deviations in both directions from a zero midpoint—ideal for physics experiments, precision amplifiers, or oscillator work .

Specifications:

Measuring range: roughly ±35 mV or ±3 A depending on the model .

Scale: About 7.5 cm with ±2.5% accuracy .

External zero-adjustment screw and binding posts for easy calibration and connection .

Transparent cover enclosing the needle, mounted in a red or black plastic case .
