Resistance Box, Electronic Type Manufacturer,Supplier and Exporter in India
Product Code : EL-E-10989
An Electronic Type Resistance Box is a precision
laboratory instrument with rotary switches or dials, using stable, high-quality
resistors (often metal film)
to set precise resistance values in labs for calibration,
testing, and circuit design, offering accuracy and stability beyond simple
fixed resistor kits, with common ranges like 1-100k Ohms and increments as fine
as milli Ohms. Unlike basic plug-type boxes, electronic ones use internal
switches for easier, more accurate selection, often featuring 5-6 decades for
broad ranges and high precision.
Designed for high-stability ohmic substitution, this electronic-grade Decade Resistance Box enables precise circuit calibration and prototyping in University and TVET laboratories. Compliant with ISO 9001:2015 standards, the instrument provides calibrated resistance increments for verifying Kirchhoff’s and Thevenin’s theorems. Its non-inductive architecture ensures linear performance across diverse frequency ranges, making it essential for advanced electronic curricula.
