Product Code : SCL-EAE-14552
A Spot Reflecting Galvanometer is an extremely sensitive instrument used to detect and measure very small electric currents.
It works on the principle of electromagnetic deflection, where a tiny current causes the coil to rotate, reflecting a beam of light from a small mirror attached to the coil onto a scale to provide magnified readings.
Commonly used in Physics Labs, Electronics Training, Optics Demonstrations, and Precision Electrical Measurements, this galvanometer is essential for understanding current sensitivity, deflection sensitivity, and null detection.
Key Features
- Highly Sensitive Detection: Measures extremely small currents in microampere range.
- Optical Spot Reflection System: Uses a mirror and light beam for precise deflection display.
- Low Friction Suspension: Ensures smooth and stable coil movement.
- Robust Coil & Magnet Assembly: Provides consistent electromagnetic response.
- Fine Zero Adjustment: Allows accurate baseline calibration.
- Sturdy Housing: Ensures durability in educational lab environments.
- Excellent Damping: Reduces oscillation for stable readings.
- High Accuracy: Suitable for precision experiments and bridge circuits.
