Linear Expansion
A high-quality apparatus to determine precisely co-efficient of expansion of various metals. An aluminium channel carries a 60 cm long metal rod enclosed in a heating jacket having three nipples for water intake, water outlet and thermometer insertion. Dial indicator is a precision instrument sensitive to 0.01 mm/division and is securely mounted. As the apparatus works with hot water, there is no danger from any steam escaping and causing burns on the skin. Complete with four expansion rods of steel, brass, copper and aluminium.

TECHNICAL SPECIFICATIONS
Eddy Current Kit
This Eddy Current Unit is a compact demonstration apparatus used to study electromagnetic induction and the effects of eddy currents. It features a conductive metallic disc mounted on a rotating shaft, supported by a rigid base. An adjustable arm allows the placement of a magnet close to the rotating disc, enabling users to observe eddy current effects such as magnetic braking, resistance to motion, and energy dissipation. It is ideal for classroom demonstrations of electromagnetic principles in a clear and interactive way.
Features:
Ripple Tank
A complete setup for demonstrating wave phenomena including reflection, refraction, diffraction, and interference. The transparent tray (33 cm × 30 cm approx.) is supported on adjustable legs for levelling. Wave patterns are observed using a mirror and projection screen, with illumination from a white LED light source in steady or strobe mode.
Features:
Hand Stroboscope Premium
A simple device for demonstrating the stroboscopic effect. The 250 mm disc with 12 slots and central handle makes rotating objects appear stationary. No power required, ideal for basic classroom experiments.
Features:
Motor Construction Kit
