LET NUMBERS TALK
Products
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.
Hook Weight Set Economy
Black Painted weights have a non-movable hook on the top. Bottoms of the weights are recessed and contain a weight below bar allowing weights to be hung from each other. Weight set includes one each of 10 gm, 50 gm, 100 gm, 500 gm and 1Kg. Two each of 20 gm & 200 gm. In plastic molded box.
MONKEY HUNTING APPARATUS II
This apparatus clearly illustrates the effect of gravity on projectile motion, making it ideal for physics classrooms and labs.
Features:
How it Works:
A spring-loaded piston launches a ball while an electromagnet simultaneously releases another ball (“monkey”). Students can observe how both objects fall under gravity, visually confirming that horizontal motion does not affect the rate of fall.
Ticker Tape Holder
The Ticker Tape Holder ensures smooth and uninterrupted supply of ticker tape in motion experiments. The strong base keeps the unit steady, while the adjustable spindle accommodates standard rolls of tape. It provides a reliable setup for studying displacement, velocity, and acceleration using ticker timers.
Features:
Aneroid Calorimeter
This calorimeter features an advanced insulated outer wall that delivers nearly five times the sensitivity of standard models. The central chamber is made of aluminum and is fully enclosed within a thick Styrofoam insulation layer; all housed inside a strong plastic casing to minimize heat transfer and ensure very low heat loss during experiments. Key features include:
Accessories (Not included): Specific Heat Cylinders Set (PH20183)
Tea Light Stand
Specially made for classroom experiments, this Tea Light Stand provides a safe and steady platform for tea light candles used as heat sources. Its durable metal frame prevents tipping and keeps the flame shielded, making it ideal for controlled heating in physics demonstrations such as convection, expansion, and heat transfer studies.
Features:
Refraction & Reflection Tank
A versatile optical apparatus designed for studying reflection and refraction of light. The apparatus is mounted on a stable base with a circular protractor and pointer for precise angular readings. Supplied with a semicircular acrylic block, prism, and mirror, it enables students to explore core concepts such as Snell’s law, total internal reflection, critical angle, and light behavior through various media. Perfect for hands-on optics experiments in schools and colleges.
Features :
Sound Kit
This compact sound experiment kit is designed for hands-on learning, enabling students to explore the nature of sound through interactive experiments. With sturdy materials such as a sound box, metal bars, string tensioners, and an ear tube, learners gain a deeper understanding of how tones are produced, amplified, and transmitted. The included illustrated manual guides them through experiments that make sound principles both engaging and easy to grasp.
Key Features:
Heat Kit
Explore the Principles of Heat.
The Heat Experiment Kit offers an engaging way for students to explore the
fascinating world of heat and temperature. Perfect for classrooms and science labs,
this kit includes a thermometer, burner, heat resistant container, sturdy stands and
Insulation cases, and all necessary accessories for better accuracies of the
experiments.
