Cropico RH9A-2 High Resistance Decade Box

The Cropico RH9A-2 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 RH9A-1 resistance calibration 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 three decades for resistance measurement from 1 kilo ohm to 100 Mega ohms, 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 1% depending on resistor setup, this decade resistor box is a very precise instrument with an impressive range of high ohm resistance decades available. The RH9A pictured above is for illustration purposes.
