CCT Metrology provides efficient, trustworthy and cost-effective Instrument Calibration Services and issues calibration certificates. Instrument calibration is a critical service for ensuring that measuring instruments and testing equipment provide accurate readings within an acceptable range. This is particularly important when precise measurements are crucial for producing high-quality products.


Our advanced calibration laboratory in China, offers hassle-free testing and calibration of a wide range of measuring and testing instruments. CCT has been a trusted name in material testing for over two decades. We take pride in providing state-of-the-art equipment and technology to ensure accurate verification and certification of your instruments. Our calibration services are ISO 17025 accredited, and all measurement results are traceable, ensuring reliable and precise calibration certificates.

At CCT Metrology, our team of highly skilled technicians has a combined experience of over 20 years in performing calibration services. We use top-of-the-line equipment to ensure that your testing and measuring instruments are properly calibrated. Our ISO 17025 accredited calibration laboratory is located in China and is fully equipped to handle all your calibration needs.

Before calibration, we record the "As Received" data for all instruments based on predetermined test points. Any necessary adjustments are then made, and the "As Left" data is documented. All calibration results, including the "As Received" and "As Left" data, are included in the Calibration Certificate along with other information required for compliance with ISO 17025 calibration standards.

Our turnaround time is quick, with standard calibration services often completed within five business days. For those who require faster turnaround, we offer expedited service. You can specify the calibration frequency of your instruments based on factors such as environment, usage, manufacturer's recommendations or other guidelines. We record the frequency in our calibration system and send automated reminders prior to the due date for re-calibration.
