Demonstration Meter, Interscale
Product Code : SCL-MBAVTOB-11909
The Demonstration Meter (Interscale) is a large-format, high-visibility analog instrument engineered for real-time classroom quantification of Amperage, Voltage, and Galvanometric deflection. Designed to meet IEC/DIN accuracy standards for educational environments, this instrument is optimized for Secondary and Vocational TVET laboratories. It solves the visibility constraints of standard bench meters, allowing for cohort-wide observation of electrical circuit dynamics.

Key Pedagogical Outcomes (Bloom’s Taxonomy)
Feature: Large-Format Interchangeable Scales. -Outcome: Facilitates "Understanding" of unit conversion and measurement range by allowing students to manually switch between AC/DC Volts and Amperes within the same circuit context.
Feature: Transparent Rear Internal View. Outcome: Supports "Analysis" of electromagnetic induction and the motor principle, enabling students to visualize the interaction between the permanent magnet and the moving coil.
Feature: Color-Coded Shunts and Multipliers. Outcome: Enhances "Application" of Ohm’s Law, as students must select and integrate the correct component to calibrate the meter for specific laboratory modules.
International Logistics & Compliance
To ensure the sensitive moving-coil alignment remains calibrated during intermodal transit, this Educational Instrument is secured in export-grade seaworthy crating (ISPM-15 compliant). Comprehensive documentation for international procurement officers is provided, including the Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ Certification, and technical user manuals in English. The Tropicalized design is validated for functional stability in environments up to 45°C and 90% Humidity, preventing coil oxidation and scale warping in equatorial climates.
Why Source from the OEM?
Procuring from the Educational Instrument OEM ensures total vertical integration, from the precise winding of the moving coil to the calibration of the interchangeable scale plates. Unlike third-party traders, our facility utilizes batch-tested for uniformity protocols, ensuring that every meter in a multi-thousand-unit tender meets identical deflection tolerances. Direct factory sourcing guarantees direct factory spares availability—including replacement pointers and scale inserts—providing a verified audit trail for high-value government educational supply chains.
