Hanna Phosphate Checker Help

[OceanicCorals-Eugene-]

This is what i do with the PO4 Checker that makes life a little easier at least for me. This method utilizes both vials provided in the kit.

*vial #1 = SW only
*vial #2 = SW + reagents

mix vial #2 outside of the checker before turning it on and time it for 3 minutes. when the timer gets to about 45 seconds left do the following:

1. Press button to turn on checker
2. wait for C1, insert vial #1
3. press button (wait for it to calibrate)
4. C2 is displayed (wait until vial #2 is done its 3minutes outside before putting it in)
5. once vial #2 is inside press the button
6. it'll give you an instant reading.

I found this easier as you can premix everything outside before starting and its just a simple swap of the vials to get your reading.

hope that helps.
