Good morning,
My question would be about the 468 MV redox calibration kit reference PS 2850 I would like to know what the little green plug is for, thank you in advance

Good morning

It is used to replace the probe during wintering or during calibration

So you meant that I remove my probe from the filtration pipe and then I put the little green cap on while I do my analysis?

Exactly,

thank you have a nice weekend
