①pHIn mode, temperature compensation can be automatically performed when the electrodes are connected（ATC）.

②When the temperature probe is not connected, it can be manually inputted.

6pHCalibration: Automatic buffer recognition, allowing electrode data asymmetry, checked every calibrationpH

Electrode status, useLovibondStandard buffer solution is used1、2perhaps3Point calibration.

7ORPdetermination:

2Various options

① “mv”Standard oxidation-reduction potential: according toDIN 38404auxiliary word for ordinal numbers6Partial requirements, transferable

change into“mvH”；

②rHdetermination:rHThe value can be obtained by measuring the oxidation-reduction potential and manually inputting itpHValue comes
