High Precision Decade Resistance Box

Model : 55X-DRB

DESCRIPTION

“RAI” Model 55X-DRB High Precision Decade Resistance Box has been designed and manufactured to simulate precision resistance and serve as a calibration standard. This decade resistance box is suitable for a wide range of applications, including Precision Resistance Calibration Standards in component manufacturing industries, component comparison in quality control, instrumentation laboratories for calibration of process control instruments, thermocouples, RTDs, temperature indicators, and engineering laboratories for resistance simulation and instrument calibration.

This precision decade resistance box provides stable and reliable resistance values for calibration and testing applications. For high accuracy, stability, and reliability requirements, Manganin wires have been used to construct the resistors. Gold-plated switches are employed in the best-grade models to provide very low contact resistance with drift-free values.

The economical models are equipped with silver-plated phosphor-bronze switches. The silver plating provides reliable switching performance and drift-free resistance values. The resistance box is available in different accuracy models to meet specific laboratory, industrial, calibration, and testing requirements.

“RAI” also offers customized Decade Resistance Box models as per customers' required resistance values and accuracy requirements.
