Hanna Phosphate / Phosphorus Checker ?

[john.o]

Well peeps I have been looking at the new Hanna checkers that are out on the market
and in particularly the Po4 checker to start off with to replace my D&D merk kit which has almost ran out, and the Hanna is only priced at £33.65 for the checker then £6.65 for 25 regent tests
so in the long run it is going to work out cheaper than buying merk kits every 4 to 5 months at £43 a pop.

Now my problem is which of the checkers do I buy, the phosphate{hi 713} or the phosphorus model {hi 716}

I would have thought the phosphate one but on other forums I have seen people using the phosphorus one. Which has confused me a little and now I just don’t know what to do for the best? Which one do you guys think I should go for?

Just a little update
after doing some more research I decide to go for the phosphorus model {hi 716 ppb}
WHY...
Well the phosphate {hi 713ppm}
Reads in parts per million and is only accurate to +/-0.04ppm
And we need a reading of below >0.03 so that’s just not reliable enough for the salty side
For e.g. the Hanna phosphate checker could have a reading of 0.00ppm on the screen but in reality it could actually be 0.04,ppm
NOW
The phosphorus model {hi 716ppb}
Reads in parts per billion
There for giving an ultra low reading of phosphorus {yes phosphorus!!}
Now I know we need a reading for phosphate and HANNA have covered this!!
All you do is take the reading from the phosphorus checker apply a simple mathematical sum and it converts the reading to phosphate and believe me I was not so sure to start with but believe me I have tested this against my D&D kit and I am well imprested
So know more expensive D&D test kits for me {£43 for 100 tests}. Just £7 for 25 tests x4 = £28 from now on


edit...

And best of all no more guess work , is it this colour is it that ask the wife ask the kids and so on

Thanks for sorting this out for us and seems it works out cheaper and is reliable, its a win, win

Yep as we all know D&D phos kits are considered one of the best on the market and I would defiantly put the HANNA phosphorus checker in the same brackets , in fact my personal opinion is its better than the D&D kit as it takes the guess work out of it

Ps cannot wait for the Hanna nitrate checker {it’s on my xmass list lol}

 

[seffieuk]

Is there a nitrate one, thought it was nitrite?

Yes seffie you’re correct there is a nitrite {model HI764} that’s out now!!!

But Hanna are also working on Calcium, Alkalinity, Magnesium, and Nitrate checkers
The nitrate checker was penciled in for release this month {September} but they have been having some issues with it , so the new date for release is December I think just in time for xmass

Cool, good to see someone using this. I had some debate about these on another forum before with quite a few people that where saying they wouldn't be that good. I liked the idea of them because like you said they are a lot easier to read (matching colours is a really poor way to get accurate results).

Might have to ask for one of these for christmas
