electronic salt water parameter test kit recommendations

[droidus]

Can anyone recommend good electronic test kits? I already have Hanna phosphate, alk and calc. I need a ph one, so at a minimum I would like one for this, as being colored blind it can be hard to differentiate between the shades of colors. Was looking at the reviews for the Hanna version, but they were so-so, so I am hesitant to buy.

I have the vertical Hanna one - it works fine (no issues).

Vertical one?
