Product Description
LEES DISC APPARATUS
For measuring thermal conductivities of poor conductors, 3 cylindrical blocks of aluminium 50 mm diameter 12.5 mm thick, with radial holes for thermometers, are clamped in a wooden frame by a screw, with 2.5 W, 6 V heating element and a set of 3 bad conductor discs.
Efficient Thermal Conductivity DemonstrationLEE'S DISC APPARATUS simplifies the study of thermal conductivity in solid metals, making it ideal for educational demonstrations. Accurate temperature measurement and efficient heat distribution support in-depth learning and reliable experimental results.
Robust Laboratory ConstructionThe main structure uses stainless steel and metal discs, mounted on a non-conducting board of wood or asbestos. Heat-resistant handles and an insulated stand ensure user safety while maintaining durability and stability during classroom or research activity.
Simple Setup & Accurate MeasurementsExperience straightforward assembly with removable discs and standard laboratory dimensions. The analog, thermometer-based display allows temperature readings with an accuracy of 1C, suitable for precise and repeatable experiments in controlled lab conditions.
FAQ's of LEEaS DISC APPARATUS:
Q: How does LEE'S DISC APPARATUS demonstrate thermal conductivity?
A: The apparatus measures thermal conductivity by heating one metal disc (usually brass or iron) with an electric heater and monitoring the temperature changes using attached thermometers. The rate of heat transfer through the disc shows the material's thermal conductivity.
Q: What is the standard process for using this apparatus?
A: To use LEE'S DISC APPARATUS, assemble the discs on the insulated stand, connect the electric heater to a 220V AC power supply, place the thermometers, and follow the manual control to start heating. Record temperature readings at intervals as heat passes through the metal.
Q: When is it suitable to use LEE'S DISC APPARATUS?
A: This device is best used during physics laboratory experiments or educational demonstrations that require examining thermal conductivity principles in controlled, indoor lab conditions.
Q: Where should the apparatus be set up for best results?
A: Set up LEE'S DISC APPARATUS on a stable, flat laboratory table, indoors, and in an environment where temperature and drafts can be controlled to avoid errors in thermal measurements.
Q: What accessories are included with the apparatus?
A: The apparatus comes with essential accessories such as thermometers, an insulated stand, support rods, and removable discs, enabling comprehensive experimental setups.
Q: What are the key benefits of using this apparatus in a lab?
A: LEE'S DISC APPARATUS offers accurate thermal measurements, simple assembly, and stable performance. Its durable, heat-resistant design ensures safety and reliability, making it valuable for teaching and research purposes.
Q: How accurate are the temperature measurements with this device?
