Service Deliverly Date

Usual delivery period: 1 week (negotiable if express delivery is required)
Delivery at the end of the year or other busy periods: 2 weeks (negotiable if express delivery is required)
Delivery in the case of time-consuming measurements: 2~3 weeks (negotiable if express delivery is required)

In the case of difficult / advanced measurement

KEYCOM will do its best to perform, by utilizing our experience developing various measurement devices. Please feel free to contact us for consultation (Note:the delivery period is longer than usual, at 3 weeks or more).

Example: Measurement method developed in November 2005→ measurement of the electric permittivity and the dielectric tangent for ultrathin films (0.01μm) with low-frequency waves.

Necessary Information

Before using our measurement service, we would like you to let us know some information about your samples via e-mail ( info@keycom.co.jp ).

Example of Information

Information listed below is very useful for us to implement measurement smoothly.

Of course, you do NOT need to answer all the questions that are unclear.

Desired frequency for the measurements
Configuration of the sample (please provide the maximum size of the object: thickness x height x width, as well as the number of samples)
Information regarding the sample material(s)
Important points regarding the handling of the sample (conductivity, volatility, etc.)
Desired temperature for performing the measurements (normal temperature, etc.)
Please provide detailed information if sample needs to be prepared by Keycom (e.g. 48% alcohol solution)
