Product Code : SCL-EAE-14552
Indian Lab Suppliers supplies the Spot Reflecting Galvanometer (Product ID: 14552) as part of its electrical and electronics range. It detects very small currents by reflecting a light spot from a mirror on its moving coil onto a scale.
Quick Answer
Current through the coil makes it turn in the field of a permanent magnet; a small mirror on the coil throws a light spot onto an external scale, which magnifies the deflection. The coil hangs on a fine phosphor-bronze suspension, giving microampere-level sensitivity, and it has zero adjustment, damping and 4 mm safety terminals. Coil resistance varies by model, typically 50–500 Ω; please confirm the coil resistance, housing, damping type and whether the lamp and scale are included at quotation.
