A history lesson
Not that long ago, most temperature sensors were analog, rather than digital. These sensors had a tendency to “drift” over time – meaning they had to be regularly recalibrated to be accurate.
What a pain.
Luckily, the electronic sensors used in modern loggers like CleverLogger do not really suffer from drift. So calibration is kind of a thing of the past.
But "Strive for 5" says I need to calibrate it
The Strive for 5 guidelines were first written when vaccines were often kept in dodgy domestic fridges and checked with mercury thermometers.
With the advent of modern vaccine fridges and digital temperature loggers, a lot of the monitoring requirements are becoming obsolete, including the requirement to calibrate the logger once a year.
It just isn’t necessary.
What about certification?
Certification is a whole different thing. Certification is checking that the Logger really does meet the manufacturer’s claims of accuracy.
We send Loggers off to a NATA-accredited laboratory where they put them into a controlled environment, wait for them to stabilise, and then compare the reading they get with the control temperature.
You then get a report back showing the margin of error in the Logger.
This testing costs $110 per logger and adds 7-10 days to your delivery.
Do you need it? Probably not. But if your governing organisation insists, the service is available to you. You can call us to discuss on 1300 80 88 89.
