Error on Elos KH test kits

[Johnny Reefer]

This isn't the first time Elos has had confusing instructions. One or two years ago alot of their PO4 kits had the wrong colour chart card. I forget exactly, but if memory serves me correctly it had something to do with European cards being different and some of these found there way into NA kits.

The Mg kit. First started using one of these about a month ago. I was missing the part where you are supposed to dump the first phase once the colour turns to green. I was adding reagent B,C, and D to the first solution. I wasted about 60 drops of reagent D trying to get the blue colour. After the first phase turns green, if they just say "Now discard this solution and repeat point 1.1" would be clearer.
There are also contradictions between the instruction sheet and the instruction card. In particular....shaking. One says to shake for "a few seconds", the other says to shake for "30 seconds".

Now the KH kit. I have one of these kits and was getting erroneous readings as well. But never bothered to look into it. Just went out and bought a Salifert kit. Kept the Elos, so I guess it will be useful when the Salifert is used up. Thanx for the info.

Other than an NO3 kit, these are the only types of Elos kits I've ever used. I wonder how many other Elos kits have, or had, erroneous instructions.

They seem to be good kits, but oy vey, enough with the instruction mistakes.

I hope people read this thread......... If you get a reading of around 14-16 dKH and decide to reduce your alk level as a result of this reading, it could end in disaster.
