Tokyo Laboratory

EMC for wide range of electronics devices -- Emission and Immunity Testing

Accreditations:VLAC, BSMI, A2LA, VCA, Mazda

Tokyo Lab. is preferably close to Tokyo metropolitan area, taking only 30-40 minutes by train, and is also easily accessible by car only to require 15-30 minute drive from each exit of Tokyo's two main express ways, Tomei and Chuo.

Equipped with the semi-anechoic chambers for testing at 3m/10m measurement distance, our test engineers are all well trained and experienced to offer you high-quality EMC testing services for all the electronic devices including medical / measurement / IT devices as well as automotive components.

Six customers can use the test facilities at the same time with separate entrances to carry in their products, which keeps customers' top confidential matters secure and safe.
