Calibration FAQ

Calibration refers to measuring, with the instrument in question being calibrated or tested against a known source.
Certification is what is granted after calibration. It is a document which confirms the accuracy of the instrument by showing the results of the calibration exercise.
A calibration certificate is an official document to show that your thermometer has undergone a calibration test in an accredited laboratory. The test date, method and results are shown on the certificate.
The calibration test compares your thermometer measurements with a traceable device or reference thermometer.
This documentation proves the accuracy of your thermometer. If the results show that the thermometer is inaccurate, it will need recalibrating. You will receive fresh documentation to show this.
Calibration certificates are not a legal requirement in the UK. Within catering applications, your HACCP plan will determine how and when your business should calibrate your thermometers.
However, a calibration certificate is the only legal document that proves your equipment is accurate. There are several benefits to this:
A calibration certificate can be used in court if a health and safety issue relating to unsafe temperature occurs.
Calibration certificates are useful for EHO visits and other inspections or audits.
Ensuring your thermometers are calibrated to a high level of accuracy will preserve the quality and safety of your temperature checks.
ETI can issue UKAS certificates for temperature and humidity instruments with internal or external probes. The standard certificate includes three different temperature or humidity points, but we can issue certificates covering anywhere from one to five points.
The more regularly your thermometers and measuring devices are calibrated and certified, the more assured you will be of their accuracy. We recommended you obtain a certificate at least every 12 months.
Yes. ETI sells a large range of calibration equipment and accessories. These include reference thermometers that are ideal for comparison checking the calibration and accuracy of other thermometers and probes, when used in conjunction with a stable temperature heat or chill source.
However, conducting calibration activities yourself may not be as accurate or provide as certain results as sending off your instruments to a UKAS certified laboratory.
We pride ourselves on providing a quick and efficient service – ETI typically completes calibration and certification within 10-14 working days.
As with any measuring or calibration activity, there will always be a probability of inaccuracy due to equipment or human error, or inconducive testing environments. Each measurement therefore has an uncertainty factor which is stated as a tolerance of plus or minus the measured figures. ETI’s laboratory offers certified uncertainties from ±0.02°C.
