Joule's Mechanical Heat Experiment Apparatus
Product Code : SCL-MH-11974
Engineered for quantitative analysis of thermal conductivity in low-conductance materials (e.g., glass, ebonite, rubber), this educational instrument utilizes the steady-state Lee’s Disc method.1 Designed for University and Advanced Vocational Physics curricula, it facilitates high-precision heat transfer experiments compliant with ASTM E1225-standard logic. The apparatus supports rigorous pedagogical modeling of Newton’s Law of Cooling and Fourier’s Law in controlled laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Dual-Disc Interface. Outcome: Enables students to establish a measurable temperature gradient across poor conductors, supporting Advanced Thermodynamics Module 202.
Feature: Polished High-Emissivity Surfaces.2 Outcome: Allows for the empirical calculation of heat loss through radiation and convection, facilitating the application of Newton’s Law of Cooling.
Feature: Suspended Base Design. Outcome: Minimizes conductive heat leakage to the environment, ensuring students achieve a high-fidelity steady-state equilibrium for accurate "k" value derivation.
Feature: Integrated Radial Thermometer Ports. Outcome: Students observe real-time thermal stabilization, enhancing data logging skills and graphical analysis of cooling curves.
International Logistics & Compliance
This educational instrument is prepared for global distribution via export-grade seaworthy crating (ISPM-15 compliant timber) to prevent transit damage to the precision-machined brass surfaces. Each unit is supplied with a comprehensive Manufacturer’s Authorization Form (MAF), optional IQ/OQ/PQ certification for institutional quality audits, and technical manuals in English. The tropicalized design is verified for long-term stability in high-humidity laboratory environments up to 90% RH.
Why Source from the OEM?
Procuring directly ensures vertical integration of the manufacturing process, from in-house metallurgical casting to precision lathe-finishing of the disc surfaces. Unlike generalist traders, the OEM maintains strict batch-tested uniformity, ensuring that the mass and specific heat of the brass components are calibrated to a standard tolerance. Direct sourcing guarantees factory-level technical support and the immediate availability of spares, including replacement steam chambers and precision-drilled brass slabs.
