Our product offering includes precision current sensing and power resistors, thermoelectric and resistance alloys, precision measurement systems and specialty items, including load banks and calibration products. We welcome the opportunity to discuss your application and look forward to finding the best solution available in our wide product portfolio.

We specialize in the manufacturing of precision current sensing and power resistive solutions for the automotive, industrial, clean energy and aerospace markets...

Isotek supplies alloys for the manufacture of all internationally standardized thermcouples (with the exception of precious metal based thermocouples) as well as extension and compensating leads for all known non-precious and precious metal thermocouples. These are supplied in the form of wire, stranded wire, ribbon, flat wire and rods for the production of thermocouples (also mineral insulated), dip sensors, quick cups, thermopiles, connectors and plugs. We also supply resistance alloys with manifold standard and special cross section in accordance with national and international standards. Our resistance alloys are supplied in the form of wire, flat wire, ribbons and sheets, foil material and stranded wire. Our resistance material is used in the production of precision resistors and potentiometers for the automotive and consumer electronics industry.

Under the new trademark ISAscale®, Isabellenhütte markets its new brand of Precision-Measurement-Systems which are distinguished through a high degree of precision and ease of operation. They combine features that are often unique in this combination.

Isotek has developed a number of specialty products, originally designed for specifi appliations, that have now become available for any interested customers. We welcome the chance to work with you to develop a product that may not be part of our standard product portfolio. Our experienced engineering staff is ready to review your specification and prints to determine what design solution may meet your application criteria.
