Client Reviews
I have worked with the folks and facility for over 15 years, and have always found the staff to be very skilled, knowledgeable and accommodating. That said, recent changes have brought noticeable technological improvements to the laboratory. I am forever grateful to have a resource like GTL available to us, and I look forward to every visit and testing opportunity and challenge.
TUV SUD America is proud and very excited to have GTL as a partner lab. We have worked with GTL for many years. GTL is strategically located in East Tennessee with easy access from most of the country. With the new management in place with many years’ experience and all the fantastic improvements to the facility we anticipate a very bright future with our relationship.
We have just completed our second project with GTL and we are extremely happy with the professionalism, efficiency, and time of completion. GTL’s staff has been extremely helpful, knowledgeable, and communicative.
We are a company that designs and manufactures Hearing Aids and Hearing Aid Accessories. We sell these products across the globe and have shared multiple test reports from GTL. We have shared these reports with various government regulatory agencies around the world, and we have yet to have a country or region question/reject any test data from GTL. We look forward to continue working with GTL in the future.
GTL’s integrity in testing, accreditations and technical expertise in EMC test standards and accuracy in the execution of the tests is why I continue to look to GTL as a professional resource for due diligence third party EMC compliance testing. Their competence and professionalism affords me with a high level of confidence in their testing and results.
