Testing Water Electronically.

Typical, twice the price as always

I can buy a few for you and ship them to you if you want...

Looks good shame they don't ship abroad though.

I am in Australia, but just found the website for the English poster. There
is an Aussie website, an American, Canadian etc. Buying one from somewhere
cant be all that hard if you really want one.

The HI-98129 is the one I use almost daily at work. It is great, and very
accurate so long as you follow the instructions precisely, and are careful
with it. These sort of meters are sensitive instruments--treat them with
the care they deserve and you will be assured of accuracy AND longevity.
(My current 98129 is nearly two years old and works like new.) I find
that
the majority of fish folks are quite negative about pH meters, and that
for
the most part their comments indicate that they dont really understand how
to treat the instrument.


I never remember the make of mine will look tonight, (I think it's German
and available in most French fish stockist)

Mine is fantastic, measures and controls my pH via a CO2 solenoid valve,
measures to the hundredth, and have never had a problem with it, makes
keeping discus, and good plants so much easier. Can't praise it enough.
Needs to be calibrated every month or so, but compared to cleaning the tank,
is hardly a burden.

Hello,

I was wondering if you guys could recommend a probe or meter which tests the
water for the following:

- Nitrite
- Nitrate
- Ammonia
- PH


I don't think that you will find an all-electronic solution for your tests except
pH. Even for pH, there are limitations to the pH probes that do the actual
sensing.

The biggest limitation of the cheap test kits that are sold for the aquarium is
that the comparison is a printed card (reflected light) while your sample is a
clear tube (transmitted light). I prefer a swimming pool test kit for pH, which
does provide a decent reference printed.

Nitrite and ammonia are easier since you are usually verifying a reading of 0 and
not trying for an accurate measurement. I don't like any of the nitrate test kits
because they all seem to produce only shades of the same hue, which is really hard
to read against a printed card.

The best bet is a colorimeter that reads the vials for you. You still have to
sample water in test tubes and dispense reagents to cause a color change. But the
reading process is much less error prone than comparison with the printed card.
Lamotte makes one that is very expensive ($650) but claims to read 43 parameters.
For about $230 you can get the Medusa CHEMITESTER 750. This one supports tests for
ammonia, nitrite, nitrate, pH, phosphate, and copper. It is available at
CustomAquatic.com. I don't have any personal experience with it.

Any ideas? I hate these damn test kits!!!

Thanks for any help! I am in the UK.

Have you tried the Jungle quick dip strips? I love them. 5 tests in
one, I am able to tell in two minutes what my critical levels are at.
