I saw them on brs website, I can order you some next time I do an order, just let me know.

Thanks, Rich. But I am not in dire need of one. However, if I walked into an LFS and saw one on the shelf would probably pick it up...

Rich you would be more than welcome, but..
It's a one time use kit.
Comes with two vials one at 0.0 that you put in first to calibrate the meter C1
Then you take second vial that comes preloaded with phosphate level at 1.00, add the little powder pack and mix. After the three minutes you get second reading C2 which in my case was bang on 1.00
If you want I can bring my calibrated meter over and we can test your water with both. If reading is the same then we know yours is accurate as well.
Let me know

Oh I get it. I thought it was premixed and all you had to do is put it in but didn't realize you had to add powder to it still. Interesting.

If you ever have time, I would love for you to come by and do a test. Thanks very much!

What if the second reading is not 1.00? Is there a way to adjust it?

So, I just tested my tank water. Phosphates = 0.
So I tested the reject water from my RO/DI, phosphates = 0.
Has anyone seen these calibration kits in Canada? If not I will order from BRS and have it shipped to a friend in Chicago and have her ship it to me.

I checked Hanna's website and I cannot see any information about what to do if your HI 713 is out to lunch, which mine obviously is. It would appear that there is no way of actually calibrating the tester. :sad:
