The High Resistance, 5kV & 10 kV Decade Box (HRRS-5kV, HRRS-10kV) is a family of high voltage decade boxes that answers the need for calibration and working high resistance decade standards that go up to 10 TΩ. High values of resistance are available for use at high voltages, without sacrificing accuracy, stability, and temperature and power coefficients of resistance.

The HRRS-5kV, 10 kV  Decade Box offers a broad choice of resistance sources that are high-range with excellent performance. These high resistance decade boxes employ state-of-the-art precision resistors of various types. They are designed specifically for operation at high voltage, with very low leakage to minimize degradation of accuracy. The HRRS-5kV and 10 kV utilize custom high voltage switches designed to handle 10 kV. The binding posts are also placed custom treated to reduce leakage.

The standard models offer a choice of one to nine decades. The panels are clearly labeled showing the step size and maximum allowable applied input for each decade. Custom requirements outside of the standard models can be satisfied.

With a resolution as low as 10 Ω and a maximum available resistance of 10 TΩ, the HRRS-5kV and 10kV Series may be used for exacting precision high-value resistance applications that require voltages of up to 10 kV.

Any HRRS that has 100 GΩ or 1 TΩ per step decades is delivered in a watertight case -WT as standard. The watertight case minimizes the effects of humidity which can cause leakage on higher resistance decades. A box containing desiccant is also attached to the underside of the front panel on watertight versions to reduce the effects of humidity. The case should remain closed when not in use.
