Based on our years of experience in the industrial sector, we recognize that there are many misconceptions among professionals regarding the calibration of measuring equipment. In this article, we dispel 7 of the most popular myths that can affect the quality and efficiency of your processes. Want to make sure your approach is the right one or avoid the pitfalls of improper calibration? Read our blog post and ensure the highest standard of accuracy for your equipment!
Calibration is a process that involves comparing the accuracy of an instrument to a specific standard called a standard or reference instrument. This helps ensure that the instrument is working properly and providing accurate results. In the context of temperature sensors, regular calibration is essential because such devices are exposed to temperature extremes, temperature changes or mechanical impacts and are subject to a natural aging process.

Although many companies are certified to DIN ISO 9000, which means they must ensure traceability of test equipment, this does not mean that anyone can perform calibrations. In Germany, for example, only laboratories accredited by the German National Accreditation Body (DAkkS) meet calibration requirements based on national standards. JUMO, which has such accreditation, offers calibration services not only for its products, but also for equipment from other manufacturers.

Although many calibrations are carried out in specialized laboratories, this does not mean that these are the only suitable places. Many components affect the result of temperature measurement, such as cables, switches and electronics. Therefore, an on-site calibration that takes all these components into account can be more accurate. JUMO is accredited to provide calibration services at your facility.
All devices, including thermometers, age over time. Various factors, such as temperature extremes, temperature changes or mechanical impacts, can affect their performance. The frequency of calibration
of measuring instruments depends on several factors, such as the type of measuring device, operating conditions and user requirements. Regular comparative measurements, in most cases more frequent than once a year, are recommended to monitor and detect possible irregularities.

Some people believe that if a device is operating with no apparent problems, it does not need calibration. In fact, regular calibration is crucial to prevent potential errors before they become apparent.
We encounter the belief that calibration is an unnecessary expense. In reality, the cost of an uncalibrated device that delivers erroneous results can be much higher in the long run, leading to production errors, poor decisions or financial losses.
Measurement errors of an uncalibrated device are a higher cost than regular calibration
Calibration quality and precision can vary from lab to lab. It is important to choose laboratories with appropriate accreditations and experience in a specific field of measurement.
Some people confuse calibration (comparing with a reference standard) with adjustment (changing the settings of a device to achieve a desired value). Although the two processes are related, they are not the same. It is possible to perform calibration without making any adjustments.
