[@julianbaccaro7733]

which is the acceptance criteria for slope and offset? does it change if another electrode is used? for example, 1230B

Dear Julian, The accepted offset is +- 30 mV in 7pH, the accepted slope is between 80 to 110%, if you consider the theoretical slope 59.16 mV/pH@ 25 Celcius degree.
