Key Pedagogical Outcomes
Feature: Integrated Dual-Pan Configuration (Upper and Lower).
Outcome: Facilitates comparative weighing in air and liquid, allowing students to calculate buoyant force and verify Archimedes' Principle with high precision.
Feature: Nickel-Plated Metallic Float Assembly.
Outcome: Provides chemical resistance and prevents volumetric expansion/contraction, ensuring that the instrument remains a constant-volume reference across multiple academic terms.
Feature: High-Sensitivity Loading Stem.
Outcome: Enables granular equilibrium adjustments, training students in the identification and mitigation of experimental parallax and meniscus errors.
Feature: Weighted Sinker Base.
Outcome: Ensures vertical stability and self-righting behavior during immersion, minimizing contact with vessel walls to reduce surface tension interference.
International Logistics & Compliance
Each Educational Instrument is secured in export-grade, seaworthy crating (ISPM-15 compliant) to mitigate transit vibration and mechanical shock. We provide a comprehensive documentation package for international tenders, including the Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ Certification, and technical manuals in English. The instrument features a tropicalized design, tested for structural and finish integrity in operational environments reaching 45°C and 90% humidity, ensuring long-term deployment in diverse geographical regions.
Why Source from the OEM
Procuring directly from the OEM ensures full vertical integration, from precision metal turning and welding to final batch-tested calibration. Unlike third-party traders, our manufacturing process includes rigorous hydrostatic pressure testing of every hollow float assembly to guarantee zero-leakage. We maintain a dedicated inventory of direct factory spares and provide institutional support for large-scale laboratory rollouts, ensuring consistency across multi-departmental procurements.
