Thermocouples and Controllers Calibration Not Necessary?

August 9, 2012

Q. It was recently stated to me that bath temps don't affect the plating quality in such a way that cannot be detected in another manner (xray for example) and therefore it was decided that calibrations on the Thermocouples and Controllers was unnecessary.

Would this be a fair statement or is it in error?

A. Hi Ken.

It is possible to overdo anything, including calibration. A quick dip of a thermometer into a tank once a week may be more than adequate.

But to skip it, believing it will be caught later is, in my opinion, just silly. It's not much different than claiming that propylactics don't have to be inspected for holes because you'll soon get reports of STDs or pregnancies if there are any :-)
