Hanna Checkers

I was wondering what the general census was regarding the accuracy of these devices? Trying to plan what kind of kits to buy.

I like my Hanna alk checker an phosphorus ULR checker. I've found both to be fairly reliable. On a per-test basis, they're not the cheapest. An old-fashioned test kit will often be cheaper than these options if you're testing fairly regularly.

I find mine accurate as well.  I have all of them.

I have the Alk and Phospate ULR checkers as well.  Very accurate in my experience.

The Alk and phosphate ULR are very easy to use and I use mine to test weekly. I also own the calcium checker which is great, but takes some practice to get accurate results.

FYI they are having a pretty good sale on Hanna Checkers at BRS......$35

If you're a casual tester, then these tests will be fine.

If you're a multiple tests per day guy like me, then they're way too time consuming.

I like my Saliferts and have been using them for the past 20 years.
