Resistance Box 500 Ohms Manufacturer,Supplier and Exporter in India

Product Code : SCL-EAE-14573

A 500 Ohms Resistance Box is a precision instrument used in physics and electronics laboratories to obtain accurate and adjustable resistance values.
It contains high-grade wire-wound resistors, connected through detachable brass or plug keys, allowing the user to quickly insert or remove resistance in a circuit.

This makes it ideal for Ohm’s law experiments, Wheatstone bridge, meter bridge, calibration work, and electrical circuit training.

Key Features

High Accuracy Resistors
Uses premium manganin or constantan wire-wound resistors for precise and stable resistance.
Plug-Type or Dial-Type Design
Smooth insertion and removal of plugs ensures long life and ease of operation.
Low Temperature Coefficient
Provides stable readings even during prolonged use.
Well-Calibrated Values
Each resistance step is marked clearly, usually in increments like:
1Ω, 2Ω, 5Ω, 10Ω, 20Ω, 50Ω, 100Ω, 200Ω, 500Ω depending on model.
Shockproof and Insulated Body
Typically made with bakelite or ABS plastic to avoid electrical leakage.
Durable Terminals
Standard 4mm or brass terminals provide solid electrical contact.
Ideal for Student Experiments
Rugged design suitable for repeated classroom handling.
