Just got a Hanna Colorimeter for alk and just want to get an idea how accurate is this compare to other kits like Elos, Salifert etc...it's the new liquid reagent not the test strips.
I have both the alk and phosphate meters from Hanna. Before they came out with the liquid reagents the powder reagents were way off. Now it's close to what my API test kit reads. I'm happy with both of my meters.
