PH-200 HM

[mosquat]

Hi all,

I tried to calibrate my PH-200 meter in ph 4.0 calibration solution. Its meant to auto-calibrate...which it sort of did but to the value of 10 ph.

Has anyone else seen this or have any ideas how to sort? Manual calibration will not let me adjust down to 4 ph...and no reply from the manfacturer.

Perhaps the only fix is a new sensor?....

Thanks

Carl

Does this help?

Haven't watched it because, well, life's too short

Cheers mate, watched it all and yeah I'm doing much the same just the calibration is way off. Hoping it can be sorted via warranty
