New Hanna Alkalinity Checker

[canesfan44]

Here's a pretty nice new checker for Alkalinity, and for $50-60, it seems to be a pretty good deal. http://hannachecker.com/index.php?p...ategory_id=25&option=com_virtuemart&Itemid=29

Is it just me, or in this economy, I don't trust any of these "ships in 4-6 weeks" stuff.

This is just great news, I hope it works, if it does i will be buying one for sure

I trust Hanna to ship it out in 4-6 weeks, it's not like they are some new company trying to make a name for themselves.

I've heard good things about the phosphate checker, so if this is as good as that, I will probably buy them both. Granted, most alkalinity tests are pretty easy, but I'm tired of trying to match the color of the vial to the little card. I would much rather see an accurate number reading then have to match colors. Hopefully they come out with a similarly priced calcium checker also.

+1
but the measurement is in ppm with an accuracy range of +/- 5ppm.

Like Rogger says if it works is one thing, but is this accuracy range OK?.

I just got home from work and am too tired to think. Maybe someone else can check this out.

Supposedly 50ppm= 1 meq/l
1 meg/l x 2.8 = dKH

is a +/-5ppm accurate enough for reef purposes.?

You bring a good point, I will check it.

 

[Rogger Castells]

5% accuracy is definitely cool, 1dkh = 17.86ppm / 17.86 x5%= .89ppm / 0.89ppm = 0.005dKh +/- per dkh unit
That is pretty accurate, I thik it is more accurate than the salifert

Rogger- Im impressed that while taking care of all those girls your still able to do these calculations. LOL.

So if will are trying to keep our tanks between 7-11dKH, what is the +/- accuracy difference when we regard 5% as a +/-?

Actually after looking further at you post: are you saying its 0.005dKh +/- per dkh unit?. If that is the case its not only more accurate than Salifert, but more than anything we have to date!!

Heres an Email I got today from hanna about the alkalinity checker I ordered a week ago

We just received about 300 of the alkalinity checkers, they are currently going through Quality Control. As soon as I get a ship date I will let you know. I’m thinking by next week they should be finished. I appreciate your patience and will keep you informed.

All i gotta say is that i have the ultra low range phosphate reader and its the best! No more stupid color charts so i would prob buy one also

That's my thought.
