Rheostat, Constantine (Eureka) Wire Manufacturer,Supplier and Exporter in India
Product Code : EL-E-10990
This Rheostat utilizes oxidized Constantan (Eureka) wire for
high-stability performance in University and Secondary physics laboratories.
Engineered for precise current regulation and voltage division. Compliant with
ISO 9001:2015 standards, the unit facilitates empirical studies of Ohm’s Law
and circuit analysis, offering current ratings from 0.6A to 8.0A. It is
optimized for sustained thermal dissipation in intensive institutional
environments.

Key Pedagogical Outcomes
- Three-Terminal
Architecture: Allows students to analyze the functional
difference between a rheostat (variable resistor) and a potentiometer
(potential divider) in active circuits.
- Oxidized
Constantan Winding: Enables learners to evaluate the
relationship between wire length and resistance while maintaining constant
resistivity despite temperature fluctuations.
- Double
Phosphorous-Bronze Contact System: Facilitates the application
of smooth, continuous resistance adjustment, ensuring steady data points
for plotting I-V characteristic curves.
- Exposed
Porcelain Core: Supports the comprehension of heat dissipation
principles and the safety limitations of current-carrying capacities in
electrical components.
International Logistics & Compliance
Science Lab Export ensures that all Rheostat units are prepared for global institutional distribution with high-integrity protection. Packaging consists of export-grade seaworthy crating (ISPM-15 compliant) featuring shock-absorbent internal bracing to protect the porcelain core from mechanical fracture. Documentation provided with each consignment includes the Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ Certification, and User Manuals in English. The assembly is a tropicalized design, tested for operational safety and insulation resistance in environments up to 45°C and 90% non-condensing humidity.
