Ready to get a Profilux

So if we should be using 7 and 9 for marine why is the KHD supplied with 4 and 7 - surely this also can affect measurements?

The KHD reagent brings the sample ph level down below 7 as a function of the test so you want the probe calibrated to the operating range.

Technically, you could calibrate all the probes with just a low (4) and high (9 or 10), but the wider range would result in a little less precision.

On an aside. I have to calibrate my probes again soon. It has been a few months

Fair enough - I did apologise before commenting but the discussion has become more involved than I anticipated. I will post on the forum then.
