Sorry if this has been asked before, but I am looking for clarification.
We are currently SQF Certified. We do not sell our product by weight. We only use our scales to measure ingredients for recipes, using generic scales you could find at your local Big box store. I have checked the manufactures recommendations on calibration but there's no option for calibration on these scales, just "zero/tare". I have certified weight standards on order to do regular verification of the scales to ensure they are accurate. With all that said is calibration by a 3rd party necessary? What about the certified weight standards? Would they need to be certified annually if they are well maintained?
Fridays are the worst for research, Thanks for the help!
