Electronic meters are superior, sure, but are you prepared for the
cost? I haven't seen one unit that monitors all those things, (not to
say it doesn't exist, due to the money involved I haven't researched
them deeply) but to give you an idea of the kind of money you're
looking at, a decent PH monitor will run you 75 US dollars (about 57
Euros) and up. From my observations, most aquaria-related products
are much more expensive in the UK.



If I could find the right equipment, I would maybe pay up to £200 - £250
(around 300 euro / 400 dollers). Obviously, I would want something which
did all the tests if possible...
They are extremely hard to find, maybe I am not looking in the right places
though...

If you see anything, let me know!
