Overall. I’m not sure this guy is worth the money. The results appear way off, the app is clunky, the screens are not overly intuitive, the regents are dated and the instructions are not included. Maybe that QR code on the box should link to instructions?
Test results;
Hanna checker nitrates HR 4.9.marine master 3.4
Apex just calibrated ph 8.19, Hanna Pen 8.1(flickered back and for between 8.1& 8.0, Marine master 7.8
Hanna checker phosphates LR .005 Maine master .009
The only test that’s close to the checker is Alkalinity…. Also, the kit came with regents that expire 9 months before the ones that came with my 6 month old checkers. Come on.
Some of the tests provide no indication of what or more importantly, how much regent to add, for example, alkalinity. You would think the app could at least tell you?
