For alkalinity I would say Elos is a good kit (or Hanna or LaMotte if you're into spending that kind of money).
For pH I wouldn't bother buying a kit as they are quite inaccurate. A handheld digital pH meter (buy calibration solution too for pH 7 and pH 10) is much more accurate.
I have a Salifert kit for alkalinity and even though it matches the calibration solution they send with the kit the kit reads 2 dKH higher than accurate, my last one was 3 dKH higher than accurate. I won't buy another Salifert kit for alkalinity.
