RH9A High Resistance / High Voltage Decade Boxes - Total Resistance 1 Terraohm - Resolution 1 kilohm - Max Voltage 5000 Vdc.

Designed using the Cropico High Quality SP1 switch combined with specially selected resistors, this range of high ohm resistance decades is ideal for the calibration of insulation test sets with a voltage rating up to 5kV. Housed in a rugged plastic carrying case with up to 9 decades the RH series covers the range 1 kΩ to 1 TΩ and is equally at home in the laboratory, workshop or field application.
