Ballistic Galvanometer Manufacturer,Supplier and Exporter in India
Product Code : ILS-PLE-10175
Indian Lab Suppliers supplies the Ballistic Galvanometer (Product ID: 10175) as part of its physics lab equipment range. It is a mirror-type moving-coil galvanometer for measuring small quantities of charge and very small currents.
Quick Answer
The coil and mirror hang between a long suspension above and a spring below, both of a special alloy chosen for high sensitivity, inside a Bakelite case with levelling screws. With a long period of 12 s, a short pulse of charge passes before the coil moves much, so the first throw is proportional to the charge. Two versions are made: 100 Ω (300 mm/µC, 1000 mm/µA, critical damping resistance 2000 Ω) and 500 Ω (600 mm/µC, 1400 mm/µA, 3500 Ω). Readings are taken with a lamp and scale; please confirm at quotation whether these are included.
