Posted 10/10/2019

DEON – Manufacturer of March Scopes has a severe quality control system in order to effectively secure and maintain the top quality.

This quality control system was established by Shimizu, CEO of DEON, who was an observer for ISO Standards Committee.

1) In order to inspect all the components, materials and processing methods etc.,

we use products which are made only in Japan within the range of our surveillance.

 

2) All the craftsmen are capable of assembling into finished products on their own.

By understanding how each task affects the quality of the finished product,

craftsmen assemble by hand with full knowledge of the importance of each task.

 

3) On conducting inspection, we compose a record for each and every scope, check all the items and fill in measurement datum.

Therefore we keep all the records for every single scope at DEON.
