DRS-900 vs Clarostat 240C

The DRS-900 series is the widest range higest power decade resistance commercially available in the world.

The DRS-900 employs state-of-the-art precision resistors of various types for high accuracy, high stability, and low temperature and power coefficients of- resistance. High-power resistors within the unit are made available without sacrificing other electrical properties.

The unit is available in 9 decades with a range of 1 mΩ - 1 MΩ. The panels are clearly labeled showing the step size and maximum voltage and current limitations for each decade.
