Resistance Substitution Box Manufacturer,Supplier and Exporter in India
Product Code : EL-E-10996
A Resistance Substitution Box (or Decade Box)
is used to provide precise, variable resistance in circuits for testing,
troubleshooting, prototyping, and calibrating by allowing users to
dial in exact resistance values without soldering, simulating components like
sensors, and fine-tuning circuit behavior.
This Resistance Substitution Box provides 12 standard
preferred values ranging from 100Omega to 470kOmega. Compliant with ISO
9001:2015 standards, it serves Secondary and Vocational TVET curricula by
facilitating empirical verification of Ohm’s Law and RC time constants. The
instrument features high-integrity terminal selection for low-loss electrical
interfacing.

Key Pedagogical Outcomes
- 12
Standard Preferred Resistor Values: Allows students to analyze
the impact of varying resistive loads on circuit current, supporting
Electronics Module 101.
- Common
Terminal Selection Architecture: Facilitates the application of
rapid component swapping in bridge circuits, reducing setup time for
Null-Point detection.
- 100Omega
to 470kOmega Coverage: Enables learners to evaluate and calculate
RC time constants across several orders of magnitude when paired with
standard capacitors.
- Visible Terminal Labeling: Supports the synthesis of complex series-parallel networks by providing unambiguous identification of resistive stages.
International Logistics & Compliance
Science Lab Export ensures that all Resistance
Substitution Boxes are prepared for immediate deployment in global
institutional frameworks. Packaging utilizes export-grade seaworthy crating
(ISPM-15 compliant) featuring anti-static internal lining and industrial-grade
desiccant to prevent oxidation of internal contacts. Documentation provided
with each consignment includes the Manufacturer’s Authorization Form (MAF),
IQ/OQ/PQ Certification, and technical User Manuals in English. The unit
features a tropicalized design, tested for dielectric stability and calibration
retention in operational environments up to 45°C and 90% non-condensing
humidity.
