[APD] Re: Aquatic-Plants Digest, Vol 13, Issue 25

Hello Tony,

Measurement of KH, i.e alkalinity, is a simple titration. It does NOT depend on any specific ion, although alkaline earth carbonate/bicarbonate is usually the principal component. If one considers pH titration, using a Ph electrode as indicator, an "electronic" method, then YES, it can be done. An automatic titrator would be ideal, although pricey!

Best,

George

Apart from measurement using a chemical test kit, it is feasible to
measure kH electronically (in the same way as pH measurement)?
