Key Pedagogical Outcomes (Bloom’s Taxonomy)
High Input Impedance (>10MΩ): Prevents circuit loading during measurement, allowing students to verify Ohm’s Law and Kirchhoff’s Voltage Law (KVL) with negligible experimental error.
3.5-Digit Resolution: Enables precise quantitative analysis of voltage drops across series and parallel resistive networks, moving beyond qualitative observation to Level 4 (Analysis) lab work.
Digital Data Acquisition: Removes subjective interpolation errors inherent in analog movements, supporting data integrity in capacitor discharge and time-constant experiments.
Ruggedized Interface: Shrouded 4mm sockets ensure electrical safety and hardware longevity during high-frequency usage in vocational training workshops.
International Logistics & Compliance
This educational instrument is prepared for international distribution via export-grade, seaworthy crating (ISPM-15 compliant) to ensure structural integrity during multi-modal transit. Every unit includes a comprehensive documentation package: Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ Certification, and technical manuals in English. The hardware features a tropicalized design, specifically tested for sustained operation in environments reaching 45°C and 90% humidity, ensuring reliability for institutional tenders in diverse geographical zones.
Why Source from the OEM?
Procuring directly from the Original Equipment Manufacturer ensures access to a vertically integrated supply chain with over 75 years of manufacturing heritage. Unlike third-party traders, the OEM maintains direct oversight of in-house PCB assembly, component selection, and final calibration against NIST-traceable standards. This integration guarantees batch-tested uniformity, direct factory technical support, and the immediate availability of critical spares for the institutional lifecycle of the instrument (10+ years).
