DEC R

A Decade resistance box is a enclosure containing number of precision resistors connected to panel terminals or contacts so that a desired resistance value can be obtained by withdrawing plugs or by setting multi-contact switches.

SCOPE offers High Resistance, High Voltage Decade Resistance Box - DecR designed using the high quality specially selected resistors. These range of high ohm resistance decades are ideal for variety of applications, having a voltage rating up to 5kV. It covers the resistance range from 1 kilo ohm to 1 tera ohm.

Features

  • Accurate and high precision resistors.
  • Compact, convenient to use.
  • Very low contact resistance.
  • Used in various applications such as:
    • Measurement of unknown resistances by the "bridge" method.
    • Calibration and integrity check of multimeters, LCR meters and calibrators.
    • In different electrical and electronic workshops and laboratories.
    • In developmental work it might be necessary to test which resistance will have the best effect given certain circuit characteristics.
    • Educational establishments.
  • Range: 1 kilo ohm to 1 tera ohm.
  • Max Voltage: 5kV.
  • Accuracy: ± 0.1%.
  • Portable, housed in rugged molded case.
