Importance of Machinery Calibration
Why is Calibration So Important?
Calibration defines the accuracy and quality of measurements recorded using a piece of equipment. Over time there is a tendency for results and accuracy to ‘drift’ particularly when using technologies or measuring parameters such as temperature and humidity. To be confident in the results being measured there is an ongoing need to maintain the calibration of equipment throughout its lifetime for reliable, accurate, and repeatable measurements.
The goal of calibration is to minimize any measurement uncertainty by ensuring the accuracy of test equipment. Calibration quantifies and controls errors or uncertainties within the measurement processes to an acceptable level.

- Machinery Maintenance
- Workers Safety
- Better Performance
- Less Error
Food Industry
Within catering, or commercial kitchens, the implications of using a piece of equipment that has
not been calibrated could be that a critical food temperature is incorrectly measured; this could
result in:
• A food safety issue
• Breach of HACCP and customers becoming ill
• Environmental Health Officer notices of closure
• Legal action
All of which result in damage to the reputation of a business. The possible cost to reputation,
when compared to the cost of a simple 2-point annual calibration, means it’s often not worth the
risk of ignoring calibration.
Manufacturing
In manufacturing process applications, any equipment used should be calibrated at multiple points across its working range to ensure reliable information to critical alarms and systems.
Failure to calibrate or improper calibration has been the cause of injury, death, and even major
environmental disasters.
