How long do pH measuring electrodes last?

Hello,

How long does a sera pH measuring electrode "last", and where do I find the manufacturing date, please?

as an average, the electrodes will last approximately 2 years from the date of manufacture. You will find the date on the shaft of the electrode itself - the code consists of 2 letters and two digits, they could, for example, look like "GP 11": the first letter codes the last digit of the manufacturing year (in this example: G = 7 → 2007), the digits do so for the month (11 = November). 

sera pH electrodes that have a seven digit code are considerably older, and are in any case way beyond the recommended usage time.
