Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Groove-Locked Nichrome Winding. -> Outcome: Prevents wire overlapping and shorting, allowing students to "Apply" constant resistance variables with mathematical precision.
Feature: Linear Sliding Contact. -> Outcome: Facilitates the "Analysis" of the relationship between conductor length and resistance through direct physical manipulation.
Feature: High-Heat Dissipation Ceramic Core. -> Outcome: Supports the "Evaluation" of high-current circuits by maintaining structural integrity under thermal stress, ensuring student safety during extended experimentation.
Feature: Triple-Terminal Architecture. -> Outcome: Enables the use of the device as a potentiometer or rheostat, supporting the "Understanding" of voltage division versus current regulation.
International Logistics & Compliance
This laboratory hardware is prepared for global institutional distribution using export-grade seaworthy crating (ISPM-15 compliant) to ensure damage-free transit across international borders. Detailed procurement documentation is provided, including the Manufacturer’s Authorization Form (MAF), Certificate of Conformity, and technical manuals in English. The tropicalized design is specifically engineered to withstand extreme environmental conditions, having been tested for operational reliability in climates reaching 45°C and 90% humidity, meeting the rigorous requirements of international TVET and ministerial tenders.
Why Source from the OEM?
Procurement directly from the OEM ensures total vertical integration and long-term institutional support. Our manufacturing facility employs in-house wire tensioning and oxidation protocols to guarantee uniform resistance gradients across the entire slider travel. Unlike secondary traders, we offer direct factory spares availability, including replacement phosphor bronze brushes and insulated slider handles. Every production lot is batch-tested for dielectric strength and resistance accuracy, ensuring that the educational instruments delivered meet the precise technical tolerances required for advanced scientific instruction.
