Calibration Equipment
Arsha Espad Shayan Company provides various calibration equipment for calibrating various parameters such as pressure, temperature, and more. All types of equipment, along with their product specifications, are introduced on the website. Every measurement instrument undergoes wear and tear due to thermal, chemical, and mechanical stresses, resulting in gradual changes in the displayed values. It is inherently impossible to avoid the wear and tear of measurement equipment over time, but it can be detected in a timely manner through calibration.
What Is Calibration, and Why Do We Need Calibration Equipment?
In today's advanced world, accurate measurement is fundamental and crucial. Incorrect measurements can lead to significant economic losses in the field of technology. Therefore, all measurement equipment (precision instruments) should have a regular quality control process in line with all relevant standards. Doing so ensures the accuracy of measurement equipment. We can only trust measurements made by precision instruments when we are certain that the precision equipment functions correctly.
Performing Periodic and Regular Calibration Will Result in the Following:
Improvement in the quality of the manufactured product
Process safety
Assurance of measurement equipment accuracy (precision instruments)
Prevention of rework and product returns
Compliance with standards and certifications
Confidence in inspections

In this process, the value displayed by the measurement equipment is compared to the result shown by another measurement device used as a reference. The reference measurement device should have proper functionality and high precision and should comply with national or international standards. When calibration is performed, the reference measurement device is used to check the accuracy of the measurement equipment in use.
Professional calibration procedures, considering standards, regulations, and various guidelines, are carried out. For a measurement instrument being calibrated for the first time, certain initial conditions must be provided. Physical conditions and what type of calibration can be performed under these conditions must be considered. In these conditions, an appropriate calibration method should be selected to match the environmental conditions.
Standards, Regulations, and Calibration Guidelines
Due to the high importance of proper calibration and the sensitivities involved in this process, guidelines and standards such as ISO9000 series standards are available and are constantly used in various countries. In ISO9001(2008) standard (Quality Management System Requirements), section 7.6 under the title "Control of Monitoring and Measuring Equipment," a specific requirement is defined that any inspection equipment affecting the quality of the product directly or indirectly must be calibrated. For example, test equipment used as a reference in the measurement room or directly in the production line.
ISO9000 series standards do not define the interval for calibration, but they require that each inspection equipment should be recorded and a distinction should be made for it to decide whether it needs periodic calibration or not.
The inspection program must be prepared in such a way that the method of work, period, type of work, and acceptance criteria are specified. Each calibration must have separate documentation with relevant details. Labels or tags must be used on precision measurement equipment to indicate which equipment needs recalibration. According to ISO9000 series standards, when a precision measurement instrument is damaged during repair, maintenance, or storage, it must be recalibrated.
