Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Precision Constantan Wire Array. Outcome: Enables the calculation of potential gradient ($V/L$), allowing students to analyze the relationship between wire length and voltage drop.
Feature: Spring-Loaded Pencil Jockey. -Outcome: Eliminates wire deformation and wear during null-point seeking, ensuring data reproducibility across multiple student cohorts.
Feature: High-Contrast Metric Graduations. Outcome: Facilitates accurate "Application" and "Analysis" levels of Bloom's Taxonomy by reducing human error during the identification of balance points.
Feature: Open-Architecture Design. Outcome: Provides visual clarity of circuit paths, supporting the "Understanding" of complex DC circuit loops and series-parallel configurations.
International Logistics & Compliance
This instrument is manufactured to meet the rigorous demands of international educational tenders and bulk institutional procurement. All shipments are secured in export-grade seaworthy crating (ISPM-15 compliant) to prevent transit damage. Each unit includes a Manufacturer’s Authorization Form (MAF), a Certificate of Conformance, and comprehensive User Manuals in English. The hardware features a tropicalized design, specifically tested for sustained accuracy in high-temperature, high-humidity environments (up to 45°C and 90% humidity), ensuring long-term utility in diverse geographical climates.
Why Source from the OEM?
Sourcing directly from the OEM ensures vertical integration of quality control and long-term asset sustainability. Our facility utilizes in-house wire calibration and tensioning protocols to guarantee uniformity of the potential gradient across the entire board length. Unlike third-party traders, we provide direct factory spares availability, including replacement jockeys and specialized resistance wires. Every production batch undergoes rigorous electrical continuity and dielectric strength testing, ensuring that the instruments delivered to your institution meet exact technical tolerances and safety requirements for educational use.
