IET Labs HRRS-F-3-1M

Through acquisition of the Genrad and ESI product lines of decade resistors, IET has become the established leader in decade resistance standards.  The HRRS Series from IET is their High Resistance line.  These products are extremely rare on the used market.  This model has a great range with six decades and up to 10,000 MOhms (10 GOhm) of resistance making it a great addition to any lab.

The IET Labs High Resistance Resistance Substituter (HRRS Series) is a useful high-resistance decade box for laboratory, test, and calibration needs. The design is implemented with special resistors, switches, binding posts, and construction.  It's designed to allow high resistance performance without sacrificing other important 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.
