About Us
Calibration for the aerospace and defence industry since 2014.
TCL Türkel Calibration Laboratory was established in May 2014 to meet the calibration needs of modern Turkish industry — particularly the aerospace and defence sector — in accordance with national and international standards.
Our founder, Fatma Türkel, served for 20 years as a senior calibration engineer at the TAI Calibration Laboratory, one of the most comprehensive private-sector laboratories in Türkiye and worldwide.
She established her own laboratory in order to carry that knowledge and experience into the Turkish aerospace and defence industry, and to help companies here obtain accreditation certificates against national and international standards.
With expert calibration staff trained on that foundation, we take pride in delivering a calibration service that is reliable, accurate, impartial and bound by the principle of confidentiality.
