Looks like some differences in testing. What is your opinion of the testing good or bad?
Not available in the states but good to see an easy testing system.
Well, I guess since we're recommended to trust the liquid test more than other kind of test kit.. then i cannot say the Pro Scan in more reliable.

I do get slightly confused with the nitrate reading too. It always measures much less than my API nitrate test but I'm starting to wonder if actually the API is at fault.
I generally use the JBL proscan as a quick, rough measurement to see if anything is wrong, then I test using liquid kits if something reads abnormal.
I actually used the separate PH 6-7.6 liquid test from JBL, so it should be more accurate than their PH 3-10 test kit. And apparently, the liquid test result matched with the proscan result.
As for the nitrate, the result of liquid test vs proscan is sooooo different. However, I'm not that worried since the proscan gave a very much higher result. So if things goes wrong, it's likely gonna be false alarm.
But yes, similar to you, I'll keep proscan for a rough measurment.
Btw, do you know how can they get the result of CO2? There're only 6 testing panels (which is the same as Easy Test strip).
