Calibration of pH meter

[lucasjiang]

Hi, recently i got a pH meter from one of the bros here. However it didnt come with calibration liquid. Hence, can i use distilled water asthe pH 7 calibration liquid? Since distilled water is also ph 7, i guess it wouldnt make much of a difference if i use it compared to a proper calibration liquid? Thanks!

Can someone enlighten me. If the calibration is wrong, what can I do?

I have a PH pen but I think the calibration is off. The screen displays -- instead of a number.

Think your probe is spoilt..

For calibration for PH meter, normally should use PH4 calibration liquid & PH7 calibration liquid for low acidic tank.. If you are using for low alkaline tank, then use PH7 calibration liquid and PH10 calibration liquid..

There should be hole behind/near lcd where you can use small screw driver and adjust it
