KEYCOM Service Center for Quality Measurements, Evaluations and Analyses

Model No. ES

Based on our accumulated experience in measurements and development of measurement devices since the foundation in 1992,

KEYCOM has dedicated itself to offering precise measurement services and devices to the customers who are in need of fast and accurate solutions.

We have various special measurement devices, such as 70GHz vector network analyzers, 110GHz scalar network analyzers, 110GHz spectrum analyzers, and 70GHz oscilloscopes, as well as a great deal of measurement experience that enable us to provide you with optimal solutions.

We welcome your contact when:

If you have problems, such as material is too thin, too small, or the measurement conditions are not easy (e.g. frequency), please frankly consult with us. We will be happy to advise you from our professional point of view.
