One of our CCP's is the water pressure used to rinse bottles before filling. Pressure gauges are calibrated every year but one of the retailer standards require the following:
"All measuring equipment used to monitor critical control points must be checked for accuracy at the start of every shift as a minimum."
The pressure is recorded every hour and the production line automatically stops when the pressure drops below the critical limit.
How would the accuracy of a pressure gauge be verified with every shift?
Thanks
