Will this kit be sold on the American market and how much does it cost and how many tests can it do?

Mac120 those are nice looking results, but what about a sample with 0 iron in it so we can see the difference between 0 and 0.1 ppm?

Zapins, 0 ppm iron will certainly result in no discoloration (/water will stay clear)
The test kit will measure iron levels from 0,008 ppm to 0,8ppm
Attached is the colour chart:



The colour chart itself is (like you see) tiny and a little bit poor, but we need to consider that this company has also a primary focus on saling their photometers for aquatic tanks.
So if you want to use the iron kit without photometer, it would be a good idea to make first some reference iron solutions and to print after doing so yours own colour chart ( for easier & better ppm reading )

@rjordan393
The kit costs 17Euro and you can use it for 40 tests.
It is not that cheap test kit, but I think the price is fairly ok if it can measure all chelated iron.
(iron II and III)

Hmm interesting. Yes the color chart helps a lot.

How much is their photometer?

I found a couple of digital photometer tests that were pretty nicely priced a while ago. I wonder how they stack up vs. the test you have? I'm not sure we can get that iron test kit you have in America.

The Hama photometers are nice, but are still single and not multi photometers - so you need to buy one for iron, one for nitrate and so on. At last you will end up expensive.

The Wasserpantscher photometer ($140-170) is a multi photometer and as far I know they have test kits for it: Mg, nitrate, potassium, chloride,phosphate, co2, ph, nitrite, kh, ammoniak, silikate, O2 (and certainly iron).
From Söll there is also a Multiphotometer availible: http://www.aqua-check.de/en/
I personaly never buyed those photometers, so I cant say anything about it.
I still know most ppl.in Germany buy photometers to check their potassium levels in planted tanks, because there are no potassium test kits around from JBL, Sera, Tetra or so.
I personally use a DIY Kalignost test for testing potassium levels and doing so works pretty fine without photometer.

Since I am mixing my own fertilizer, I am certainly somehow interested to test uptake rates from stuff like zn, cu, boron - unfortunatly there are no affordable photometers around which can measure each stuff.

I am not sure, I think you need to ask them - perhaps they will ship the iron test kit abroads?
