Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Fine-Pitch Micrometer Screw. -> Outcome: Enables students to calculate the sagitta of a surface with sub-millimeter precision, supporting Applied Optics Module 102 (Curvature Analysis).
Feature: 100-Division Circular Scale. -> Outcome: Facilitates mastery of the vernier principle and error analysis, allowing learners to analyze measurement uncertainty in General Physics Metrology.
Feature: Double-Disc Ergonomic Interface. -> Outcome: Provides enhanced tactile control for precise "point-of-contact" identification, reducing mechanical backlash during Experimental Lab Verification.
International Logistics & Compliance
Our global export operations prioritize the integrity of sensitive metrology hardware.
Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring die-cut internal shock absorption to prevent decalibration during intercontinental transit.
Documentation: Shipments include a Manufacturer’s Authorization Form (MAF), Batch Inspection Reports, and comprehensive Technical Manuals in English.
Durability: Tropicalized design specifications, tested for reliable operation and corrosion resistance in environments up to 45°C and 90% non-condensing humidity.
Why Source from the OEM?
As an Original Equipment Manufacturer, we maintain total vertical integration over the production of educational instruments. Unlike traders, we perform in-house precision threading and metallurgical hardening of the tripod legs to ensure batch-to-batch uniformity and longevity. Our factory-direct model guarantees the availability of technical spares—including replacement central screws and scale assemblies—for a minimum of 10 years, ensuring long-term institutional ROI and direct factory-level calibration support.
