KEYCOM Service Center for Quality Measurements, Evaluations and Analyses

Model No. ES

KEYCOM has not only developed measurement devices and systems based on its advanced technologies for products in the 10μHz~300GHz (VHF/UHF/Microwave/Millimeter wave) field, but has also refined its measurement technologies for a wide variety of materials over 25 years of providing measurement services.

In addition to our original measurement equipment, we also own a 110 GHz vector network analyzer, a 110 GHz scalar network analyzer, an 80 GHz spectrum analyzer, a 70 GHz oscilloscope, and various other measurement equipment.

This allows us to cover the measurement needs of most materials, including solids, sheets, films, powders, liquids, and multilayer structures.

Please feel free to contact us.

We will be happy to advise you from our professional point of view.
