📋 Product Overview
The Standard Resistance Box SRB-9 is a dependable and economical reference instrument designed for resistance calibration, verification, and electrical testing. It offers a selectable range from 100 micro-ohms to 10 kilo-ohms with ±0.5% accuracy, making it well suited for routine measurement and industrial laboratory applications.
The resistance coils are constructed from manganin wire, known for its stability and low temperature coefficient, ensuring consistent resistance values over extended usage. The instrument provides nine fixed resistance steps via easy-to-operate slide switch selection, allowing fast and accurate resistance setup.
With moderate wattage handling and clearly rated current capacities across the full resistance range, the SRB-9 integrates effectively with Kelvin Double Bridges and Digital Micro-Ohm Meters. It serves as a practical reference standard for calibration tasks in wire & cable manufacturing, test laboratories, educational institutions, and quality assurance departments.
