HARS-X2-6-0.1 Hộp kháng Decade công suất cao

The HARS Series is the best choice when you need a laboratory grade, tight tolerance, high performance resistance decade box that is also cost effective.

The High-Accuracy Resistance Substituter (HARS) resistance decade box is a family of instruments providing a very broad choice of high performance resistance sources. With a resolution as low as 1 mΩ and a maximum available resistance of over 111 MΩ, the HARS series resistance decade boxes may be used for exacting precision measurement applications requiring high accuracy, good stability, and low zero-resistance. Any number of decades from one to eleven is available in a choice of accuracies.

The HARS resistance decade box is a precision resistance source with excellent characteristics of stability, temperature coefficient, power coefficient, and frequency response. The HARS Series employs very-low-resistance switches with silver alloy contacts. A special design keeps zero resistance to less than 1 mΩ per decade for the HARS-X. Self cleaning keeps the silver contacts from becoming tarnished when unused, or when only low currents are passed through them. This is most often the case when only minute test currents are drawn by digital multimeters or other test instruments. Contact resistance is stable and remains low and repeatable.

The HARS resistance decade boxes have high-quality gold-plated tellurium-copper binding posts serve to minimize the thermal emf effects which would artificially reflect a change in dc resistance measurements. All other conductors within the resistance decade box, as well as the solder employed, contain no metals or junctions that could contribute to thermal emf problems.
