PH - Calibration
Started by ahmed al heseky, Nov 11 2011 07:58 AM
Good morning all....
I have two questions
1 - How is the work of calibration device for pH?
2 - What is the time required between each other and calibrated according to ISO 9001 and ISO 22000?
--------
Thank you very much...

Dear,
First question as i understood that how calibration has importance to pH meter. Actually calibration compensates deviations of asymmetry potential and slope of the electrode over time. calibration with buffer ( two or three point calibration) solutions corrects variations in the electrode response.
Calibration frequency may be between oh and 7 days, but mostly programmed for daily calibration (three step daily is recommendable).

How many passes of the wands do we need to do the daily metal detector calibration?
