Hanna Phos Checker

[krzyphsygy]

Having issues with mine. Just got it and it is hard to use. When I put the sample in the checker for the first time to clear it then hit the C2, I pull the vial out and open the sample to put in the powder and every time I dont get the powder in all the way before that unit shuts off. Now what???

How can I recheck the dang thing or clear it or what ever when the vial now hasd the powder? So I have to use both vials, one with sample water and the other with the powder just to complete the test.

Does this sound right?

Some people have used both vials however it isnt recommended as it could get a diffrent reading through both vials.

I dump all the powder onto a piece of paper and have it ready then when i am ready just fold the paper to a funnel and in it goes. Much faster than the packets imo

Great Idea, thanks

[Robert1969]

I like that idea as well. Good tip thanks

[fishyguy7]

I also get the powder out of the packet first. Works much better that way

Selling mine, jeez I hated the number of steps. Could not get it on first try ever.

[shifty51008]

Its 3 steps, how much easier do you want it lol

I don't really like this unit either. I get a different result every time i test, sometimes I'll do it 3x in a row And get 3 different answers. I like the paper idea, I have been cutting two sides of the pouch open with a razor and using the pouch to pour it in. I did notice that if you don't cut the pouch open on two sides to open it all the way, a decent amount of powder gets stuck in the creases and can be left out of the vial. I wonder how much the test would vary depending on whether or not you get every grain of the reagent powder into the vial...

Why don't you just cut cut two sides of the packet make it funnel and have it ready for step two, that's how I do it very simple.

I havent had problems getting reproducible results, possibly a defective unit?

Use the same cuvette for C1 and C2 for accuracy.
Before you start, prepare your reagent package, I like to cut it in half along the diagonal, then fold out the two sides until I get a diamond shaped cup.
After zeroing out the first cuvette, when the meter displays C2, you have 2 minutes before the meter turns off. Start a timer and begin adding reagent and mixing.
Right before the unit times out, press and hold the black button, this will start a 3:00 minute timer. Continue to mix during this time.
With seconds to spare, put the cuvette back into the checker facing the same direction that it was for C1 (I use the 10ml marking to tell which way it is facing).
Using this method will give you plenty of time and accurate results.

Time Consumer, jeez how many steps and things to keep track of? One of the reasons I do not like this checker.

give me an example of what the 3 test readings your are getting? like .03 .0 and .05?

+1 this is the way it's done...... mine actually can go at least 2.5 minutes before it times out. this is plenty of time to disolve the reagent leaving the 3 minute timer for reaction time.

IMO, 5 minutes of my time and a regimented ritual is worth having confidence in the results.

[karsseboom]

It's very easy to use. It's a little more work then most test but its not hard at all.

I haven't done tests in a while, I'm overdue. The spread was Somethjng like that, I don't fully recall

[shifty51008]

If the spread was close to what i pointed out then it is still working correctly as it has a. 03 tolarance so even if you get a reading of 0 it could actually be. 03.

Having a tiny funnel is also super useful.

[mikecc67548]

If you want to use 2 cuvettes (test tubes, but notice no "r" in it) I zero them against each other, then add my reagent to 1 and restart test, using other as zero,
