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.

THanks, very helpful. where is a good place to buy the handheld Ph testors??
