Does anyone have a Merc/D-D PO4 test kit?

Tony what kind of meter do you have. I have a Hanna colorimeter and from the looks of my work schedule will be in Calgary a couple of times in the next month or so. I could bring it down with me if you like but I will be staying downtown so you would have to come and get it and bring it back. I think I will be there for 4 days in the middle of June.
