I picked up one of the new Hanna HI783 Magnesium checkers when they dropped last week, and after one or two mulligans I got it working pretty well.
A little more complex than the basic hanna tests (requires 2 reagents) but nothing too bad, especially vs the other titration mag methods. The toughest part is getting a precise measurement on the syringes, I find them inconsistent.
Step 1: Add 4ml reagent 1 (HI783A-0) into dry cuvette
Step 2: Add 5ml aquarium water to cuvette
Step 3: Invert a few times/add to tester and press C.1
Step 4: Add 1ml reagent 2 (HI783B-0) which will bring to cuvette 10ml fill line
Step 5: Invert a few times.add to tester and press C.2
Worked well on a control test with 35ppm RSP, reading 1388 (package says 1350), and on informing me my DT is overdosed (1800+ x_x)
Im happy with it - will definitely keep it in the Hanna toolkit. What do others think about the new tester?
