another hanna phosphate checker problem

drukkosz · 05/01/2012, 10:29 AM

So i did call hanna today, explained my problem. Again the checker stops when counting down from 3 minutes to 0. Is stops on random 30, 16, 14 seconds. It doesnt happen every time, I would say probably 30%. Which is very frustrating because you only get 6 regents in the package.

So the tech on the phone never heard about that problem (yea that’s a good sign for me!) and asked me 5 times if i am sure its not my actually test result. wow!!!

Also i was told that the checker has 0.04 accuracy. Meaning if your result is for example 0.10 then your real result could be 0.06 or 0.14?? Seriously if i knew that before i would never bought that thing. Especially when your phosphate should be below 0.03
I was told that I need to send it back so the tech can test it. Knowing my luck he will test it once or twice and it will work fine and will send it back to me. Not mention that I have to pay for shipping to get it to them. And this is second checker that I got in two weeks. First was not functioning at all. Every time I opened the lid it shouted itself off.

for the accuracy,test the first time normally and then test a few more times using the 2 vial method and average.....

my point is why sould you have to do it when you spend $50 for a checker and extra $10 for regents. It should just work!

you dont have to do it....if you want check the accuracy thats a good way....the ulr phosphorus meter that i use is always within a couple ppb....theyre very accurate

+1, dru I think you grabbed the least accurate checker.

i think its just my luck. everything that i buy doesnt work, comes broken or missing pieces. i really dont get it

clydog · 05/01/2012, 12:54 PM

this may be a blessing...since its broken, have them exchange it for the more accurate/better suited ULR phosphours meter

clydog · 05/01/2012, 12:55 PM

also with the 2 vial method you only use 1 packet of reagent

lol, did i mention that this is my second meter within two weeks??? the first one didnt work at all!

tell them you want the ULR since there have been so many issues with the regular one.....you bought the wrong one to begin with

Are we supposed to be using the phosphorous checker & not the phosphate checker? Why is the difference between the two?
