Cropico RH9A High Resistance Decade Box

The Cropico RH9A is a high resistance, high voltage decade resistance box that has been designed using the Cropico high quality SP1 switch and specially selected resistors. The RM9A decade box is ideal for the calibration of insulation test equipment that has a voltage rating of up to 5kV. This high precision resistor substitution box has nine decades for resistance measurement from 1 kilo ohm to 1 Tera ohm, perfectly suitable for use in both the laboratory workshop or in the field. With a resolution of 1kΩ and an accuracy from 0.1% to 2% depending on resistor setup, this resistance calibration box is a very precise instrument with an incredible range of high ohm resistance decades available.
