Do accurate electronic test kits for Ca, Mg and Kh exist? Which ones are the best?
I HATE the Hannah tests and do NOT find them accurate at all. I honestly think one is better off taking $50 out back and burning it as opposed to buying a Hannah device.
I have the Alk checker (new one) and have been through numerous communications with their customer service. I have been sent regents, calibration solutions to check, and even had them take my unit in to check. The issue with their calibration is the range that it gets the unit to within. The unit no matter what tests low though fairly consistantly low so I can use it BUT no way should it be used alone IMHO.
I have learned it is typically 1.5-1 DKH too low to what the tank actually is. That .5 is a large swing IMHO though when I try to leave things at 8.3 exactly in my tank. At this stage I have given up on it and pretty much use either salifert or my new favorite the Lamotte kit which is SUPER easy to read.
This isn't typical at all. Sorry if you've had a bad experience, but Hannah checkers are the best hobby-grade tests you can get, *particularly* the Alk checker. It sounds like you are going wrong somewhere with the test. The vial can't have any dust or fingerprints on it, so you should wipe it clean with a microfiber cloth before EVERY time it is going back into the checker, which is twice for the Alk test.
Been there and gone through it all. I have also had skype calls with CS from hannah.
And I would not say it is far from typical. Stories abound about how bad they are. They might be the best hobby grade electronic test but with the bar so drastically low that is not a great confidence boosting statement...

I found Hanna testers to be a giant PITA and sold them. I fail to understand why people like them. But to each his own. Just not my cup of tea.
