The High Resistance (HRRS Series) is an economical, high-performance, high-resistance decade box for all laboratory, test, and calibration needs. The High-resistance design is implemented with special resistors, switches, binding posts, and construction-design to allow high resistance performance without sacrificing other electrical properties. These instruments are useful wherever small currents and high resistances are required,

The HRRS Series employs state-of-the-art precision resistors of various types for high accuracy, high stability, and low temperature and voltage coefficients. The standard models offer a choice of one to seven decades. For custom units, models up to 11 decades are available . For higher voltage or higher resistance, models up to >10 kV and 10 TΩ are also available in the HRRS-5kV & -10kV Series.

The binding posts are for the HRRS high resistance decade boxes are insulated with Kel-F high-resistance, non-moisture-absorbing material ensure low leakage.
With a resolution as low as 10 Ω and a maximum available resistance of over 100 G&Omega, the HRRS Series may be used for exacting precision high-value resistance applications.

The HRRS series decade box complements the HARS series which provides resistance steps as low as 1 mΩ. The units may be rack-mounted to serve as components in measurement and control systems.

HRRS High Resistance Decade Box Applications

  • calibration of meters and megohmmeters,
  • checking of electrochemical and biomedical sensors and instruments.
  • testing high-impedance amplifiers and the insulation of low-power circuits.
