Central to the operation of Unit 3 Compliance is our EMC test laboratory. We are well equipped to perform a wide range of tests and all testing is performed by experts. We can support you in many ways from quick look-see and pre-compliance tests through to final EMC measurements for self certification.

We work to the guiding principles of ISO 17025 but are not UKAS accredited allowing us to offer a good balance of quality and value in EMC testing services.
