Calibration is a series of measurements. Under certain conditions, it is the activity of measuring the accuracy of any other test and measuring instruments and determining their deviations if they are used by a previously determined standard or system. The science of metrology is a science of measurement, covering all practical and theoretical topics, which are based on the field of science and technology, regardless of its uncertainty. The success of the manufacturing companies is based on the ability to produce and sell the products that have been produced with precision measurements and which have been checked and tested. In terms of human health in the field of medicine, precisely diagnosed at critical times and reliable analyzes are of great importance. It is a requirement of the quality, speed and reliability of the service provided that all tools and materials used in testing, measurement and analysis in laboratories provide accurate, precise and reliable results. In short, all forms of measurement, physical, chemical or biological, affect the quality of life.

In our country, a feasibility study related to calibration was carried out by TÜBİTAK in 1981. In 1988, laboratories were established by the Turkish Standards Institute and calibration services were started. With these studies, it has been ensured that various weighing and control tools used in production work by manufacturers in a manner recommended in international standards.

The International Unit System or the International Measurement System, defined as SI in short, was adopted at the 1960 General Conference on Weights and Measurements. This system has been proposed for use in technology and science. In this way, technical communication integrity is ensured worldwide. For example, meter (m) in length measurements, kilograms (kg) in mass measurements, amps in time measurements (A), measurements in thermodynamic temperature (Kel), measurement of light content in Candela (cd) and substance content. based on the molecule (Mol). Apart from these, other measurement units have been determined based on this basic unit of 7.

Calibration is the comparison of a measurement instrument with another instrument at the same level or at a higher level, generally in laboratory, and documenting the results. For the reliability of the results, the accuracy of the instrument used for the calibration must be at least three times more accurate and better than the accuracy of the calibrated vehicle. Calibration studies do not mean a repair. This condition is detected only if the calibrated vehicle is measuring incorrectly. If a faulty vehicle is repaired, it must be calibrated if necessary. Calibration work is not an adjustment process. This tool must be calibrated once again after the settings of the vehicle have been measured incorrectly.

With the calibration studies, the accuracy of all measurements is ensured, the product quality is increased to the desired level, the differences that may occur during the production are eliminated and the products are compatible with the competitor products. At the same time, the enterprises are adapting to the advanced technology and have superiority against their competitors. Likewise, the products are found to be in compliance with international standards.

Fast, high quality and reliable calibration works are carried out in advanced laboratories. During these studies, standards and calibration methods published by domestic and foreign institutions are taken as basis. The following basic studies are carried out within the scope of calibration studies:

• Calibration of balloon Joje
• Temperature Calibration in Controlled Volumes (Oven, Incubator, Liquid Bathroom, Refrigerator, Deep Freezer) (between -40 Degrees and + 200 Degrees)
• Piston pipette (micropipette) calibration
• Calibration of balance (non-automatic weighing devices)

Laboratory calibration services, domestic and foreign organizations TS EN ISO / IEC 17025 is accredited in accordance with the General Conditions for the Qualification of Test and Calibration Laboratories. These laboratories operate in accordance with current legal regulations, generally accepted testing methods and standards published by local and foreign organizations.
