To me the real "dream" of electronic measurement for Ca and Alk would be to add probes to a controller and the controller can measure the gap between what's added and the consumption rates as a function of time. However the technology really just isn't there for alk testing via probe (I did read an interesting article about this a few months ago about how the physics really just wasn't there for a good electronic Alk measurement) and even though the capacity exists for doing this Ca already, it's really more important to track Alk, or at least, without tracking Alk at same time as Ca, then the Ca number doesn't hold a lot of meaning.
So anyhow now that they claim to have figured it out for Alk, I am naturally curious to see how well it will shape up.
If however it is a colorimeter based tester like then realistically it is just a replacement for manual testing and you can ignore controllers from the equation. In which case it has to be about convenience, accuracy and precision. And repeatability. It's already pretty convenient to test Alk, it has to be one of the easiest tests out there, but for Ca is starts to get a little into the weeds and really into the weeds usually for Mg, so one could maybe accept a little loss in the area of Alk for the sake of gains in the areas of Ca and/or Mg in the hopes that overall to test the big 3 becomes easier than the titration based tests for all 3.
I dunno though. I would like to see the products released and then give them a try. The science alone for the Alk is interesting to me so we'll see how they shake out.
