I have always used the liquid/dropper bottle type of of testing for water parameters but am wondering if there is an alternative/better option (digital meters etc).?

Most use the liquid reagents like you but for pH and TDS there are meters. I don't see the need for the extreme accuracy.

I use a pH meter but had to go through two others before I found one that the calibration appeared to work properly and the unit stayed accurate. I find it more convenient leaving aside the trouble calibrating it.
