As an AAMA accredited testing laboratory, QED LAB is fully committed to “independence”. We are a professional field testing agency that performs testing and diagnostic services only.

Our clients have the complete peace of mind in knowing that QED LAB has absolutely no involvement or financial interest in contracting (remedial repairs) or consultation.

We focus on the job at hand – testing the product or system. Once having done so, our nationally recognized accreditation as a completely independent, impartial, objective testing agency provides you with a qualified, unbiased third-party evaluation that you can rely on.

Our diversified experience and complete independence allows QED LAB to bring confidence to the table, not just test data.
