Hello,

I've got an issue with KHD accuracy.
Several tests running on GHL reference solution (7,5 dKH) gave measurement results at 8,5 dKH.
Pump heads are calibrated, water sample tube volume checked, probe calibrated in disposable liquids, water sample at max 100ml
I think it over and have no clue about the possible cause.

Thank you in advance for reply

Regards,
Kinga
