Calibration Laboratory

Argesim Teknoloji established its Calibration Laboratory in 2022 within its production facility in Çorum, in order to support the R&D and Quality Control processes of the meteorological instruments it manufactures.

Since its foundation, our laboratory has aimed to:

• ·         Fully comply with the technical and administrative requirements of TS EN ISO/IEC 17025

  ·         Provide all calibration services needed for meteorological sensors in the sector

  ·         Help close the gap in professional calibration services in this field

In line with TS EN ISO/IEC 17025, we submitted our accreditation application to TÜRKAK (Turkish Accreditation Agency) in 2025.

  

TÜRKAK has signed a multilateral agreement with the European co-operation for Accreditation (EA) and a mutual recognition agreement with the International Laboratory Accreditation Cooperation (ILAC), ensuring international recognition of TÜRKAK calibration certificates.

 

Closely following the latest developments in technology, Argesim Teknoloji, with the support of its calibration laboratory, is able to manufacture high-accuracy instruments and, upon request, calibrate these devices in line with IEC standards and international norms. The reliability achieved through advanced calibration and test equipment builds the confidence of our users.

 

Our Vision

  

Our Mission

 

As Argesim Teknoloji Laboratory, our mission is to:

·         Produce results with high precision and reliability,

·         Provide customer-oriented, quality-driven calibration services, and

·         Set the standards in the field of calibration.

• 
  

In all laboratory activities, we are committed to the principles of impartiality, confidentiality, technical competence and continuous improvement, with the goal of becoming a globally recognized and preferred laboratory.

An integral part of our mission is to:

• ·         Support the continuous development of our staff,

  ·         Implement environmentally conscious practices, and

  ·         Create value for society through our work.

•  

Quality Policy

 

Our quality management system is based on the TS EN ISO/IEC 17025 standard and a risk-based approach. With our qualified staff, equipped with all necessary technical resources and strictly following system documentation, our primary objective in calibration services is to ensure sustained customer satisfaction, while adhering to the principles of transparency, confidentiality and impartiality.

As laboratory management, we undertake to:

• ·         Conduct all calibration activities in accordance with the standard,

  ·         Continuously improve the effectiveness of our existing system, and

  ·         Implement and maintain measures based on the analysis of identified risks and opportunities.

Our laboratory’s competence has been demonstrated through services received from various organizations—both in Turkey and abroad—that have been independently audited and have sectoral experience serving different companies.

The knowledge and experience of our personnel are continuously monitored and recorded through in-house trainings and inter-personnel comparison methods.

 

What is Calibration and Why Is It Necessary?

 

1- What is calibration?

Calibration is the process of comparing a measuring instrument whose accuracy is uncertain with a reference instrument whose accuracy is known and traceable, and reporting the measurement results.

What calibration is not

Calibration is not:

• ·         An adjustment

  ·         Maintenance

  ·         Or a repair operation

• 
  

2- Why is calibration necessary?

Calibration is required to determine how close the readings of a measuring instrument are to the true values.

3- Is calibration mandatory?

The obligation to calibrate depends on:

• 4- When should calibration be performed?

Calibration should be performed:

• ·         When the device is first purchased,

  ·         After any repair, adjustment or maintenance,

  ·         Whenever there is any doubt about the measurement results, and

  ·         At defined regular intervals.

• 
  

5- Does a calibrated instrument have zero error?

Calibration is not an adjustment or error correction process. Therefore, a calibrated instrument does not mean an instrument with zero error.

6- When does a calibration become invalid?

Calibration becomes invalid if, after calibration:

• 
  

• ·         The device is dropped, subjected to impact or damaged, or

  ·         The calibration interval has expired.

7- What happens if I do not calibrate?

Sound decisions can only be made based on reliable data.

Decisions and actions based on incorrect measurements can lead to loss of reputation, wasted labor and financial loss.
