Measurement service

professional measurement service

We strongly believe the professional measurement service is one of the most important contributions for our customers and the industry to move forward their business as quickly as possible.

For more information

Proper sample preparation is the first step to accurate measurement.

Since the size of the sample is used to calculate the permittivity and permeability, the sample size measurement error directly affects the permittivity and permeability.
