Habib,
You are correct in both statements. My screen name is my name backwords and on my last test the Sailifert kit read 430 and the Hach gave me a 464.
I assume the Sailifert test is more accurate because it uses the titration syringe vs. counting drops for the Hach.
I like to use the Sailifert test better and it costs alot less too. The only thing I would like is for the Sailifert to have a plastic case like the Hach instead of just the cardboard box.
