Resistance Box, Plastic Manufacturer,Supplier and Exporter in India
Product Code : EL-E-10995
This non-inductive Resistance Box provides a calibrated
accuracy of ±0.1%. Engineered for high-precision circuit calibration and
Wheatstone bridge balancing, Designed for University and Secondary level
physics curricula, the instrument utilizes double-silk covered constantan wire
and split-brass contact blocks to ensure minimal thermal EMF and stable ohmic
values. Complies with ISO 9001:2015 standards for institutional procurement and
technical tenders.

Key Pedagogical Outcomes
- Non-Inductive
Bifilar Winding: Allows students to Analyze and verify
resistance values in both AC and DC circuits without inductive reactance
interference.
- Interchangeable
Brass Plugs: Enables learners to Apply the principle of series
resistance through tactile manipulation, facilitating manual circuit
configuration.
- Constantan
Wire Construction: Supports the Evaluation of
temperature-coefficient effects, as the material maintains stability
during sustained current flow.
- ±0.1% Calibration Accuracy: Facilitates high-resolution data collection, allowing students to Synthesize precise mathematical models for Ohm’s Law and Kirchhoff’s Voltage Law.
International Logistics & Compliance
Science Lab Export ensures that all precision
resistance standards are prepared for global institutional distribution.
- Packaging:
Export-grade seaworthy crating (ISPM-15 compliant) with anti-static
internal padding and moisture-barrier lining to prevent oxidation of brass
contact blocks.
- Documentation:
Consignments include Manufacturer’s Authorization Form (MAF), IQ/OQ/PQ
Certification, and technical User Manuals in English.
- Durability:
Tropicalized design explicitly tested for dielectric stability and
calibration retention in operational environments up to 45°C and 90%
non-condensing humidity.
