Product Code : SCL-EAE-12253
Laboratory Spot Reflecting Galvanometer (SKU SCL-EAE-12253) is a sensitive instrument that detects very small electric currents and shows the deflection as a reflected spot of light moving over a scale. College and school physics labs use it as a null detector in bridge and potentiometer experiments and to demonstrate galvanometer sensitivity and current direction. Science Lab Supplies manufactures it in Saha, Ambala, India, at Plot 448, HSIIDC Industrial Area, and supplies it straight from the factory to schools, colleges, tender contractors and distributors.
Specifications
The confirmed details of this galvanometer are listed in the table below. In short, it is a light-spot galvanometer: a small current deflects the moving system, and a reflected beam of light magnifies that deflection on a scale, so even tiny currents and the exact balance point of a bridge can be seen clearly.

Applications and Experiments for the Spot Reflecting Galvanometer
The galvanometer is used wherever a circuit must be balanced to zero current or where currents are too small for an ordinary meter. Typical uses are Wheatstone-bridge and potentiometer balancing, low-current detection and demonstrations of moving-coil deflection in college physics lab equipment in India.
- Class 12 physics: finding the balance point in resistance comparisons on a Post Office Box Plug Type.
- B.Sc. practicals: null detection in emf and resistance measurements on a Potentiometer with Jockey Pencil, with current applied briefly through a Tapping Key Physics Lab.
- Demonstrations of galvanometer sensitivity, deflection and current direction.
- Engineering and diploma labs: detecting low currents in bridge and network circuits.
Set the instrument on a firm, vibration-free bench, keep it away from shocks that could harm the suspension, and connect it only to low-current circuits.
Standard Scope of Supply
The Laboratory Spot Reflecting Galvanometer is supplied as one main unit as described above. Sensitivity, coil resistance, scale format, leads and any spare lamp for the model you choose are set out on the quotation; bridges, potentiometers and keys are quoted as separate items.
Packing, MOQ and Lead Time
Quotations are available for one galvanometer or for a set covering every bridge and potentiometer bench in a lab. Science Lab Supplies lists packing, delivery time and price for the quantity requested, and bridges, jockeys or keys can share that quotation.
Using its Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. Contact the team through the contact page, add items to the enquiry cart, or follow the lab tender page for tender enquiries.
Frequently Asked Questions
Why use a light-spot galvanometer instead of a pointer type?
A reflected light beam acts as a long, weightless pointer, so very small deflections become easy to see. That makes the balance point of a bridge or potentiometer sharper than with an ordinary pointer galvanometer.
Can it measure large currents directly?
No. It is a detector for very small currents. Large currents can damage the delicate moving system, so use it only in low-current circuits such as balanced bridges and potentiometers, and apply current briefly with a key.
How should the galvanometer be looked after?
Keep it on a stable bench away from vibration, avoid knocks to the suspension, store it in a dry, dust-free cabinet and clean the case gently with a soft, dry cloth after each session.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The galvanometer is produced at its works in Saha, Ambala, India, and you receive your price and delivery terms from the factory rather than from an intermediary.
