Accreditation Filed
As an Internationally Certified Calibration Laboratory,
HCT is the first in Korea to develop automated calibration software and received KOLAS accreditation in particle counter, airplane take-off and landing system, and 40 GHz in RF field calibration. HCT is making efforts to pioneer new fields and is also first private calibration laboratory apart from KRISS, national standard body, to provide calibration services in the acoustics field such as microphones, piston phones, sound level calibrators, and others.
In addition, HCT performs calibration for automobiles, test certifications, semiconductor, pharmaceutical, aerospace industry fields, and others that require specialized calibration technologies. To lead measurement technology with highest calibration services in Korea, HCT is making efforts with active investment and continuous improvements on technological capabilities.
