Hi, understand this maybe obvious for a lot of people but if anyone can let me know how they use the reference solution to test the kid as well as your regular test kits (such as Hanna All Checker) I would be most grateful.
KHD: my guess is that I will add the number of ml required to perform a kh test to a separate graduated container, drop the sample water tube inlet into that container and perform the measurement? Follow up questions: would it be required to completely flush the measurement cell prior to doing such a test in order to avoid contamination from residual tank water?
Hanna Checker: I have tried setting the baseline with RO and than fill the cylinder with the reference solution but the result came out zero. I than filled the cilinder with the reference solution, zeroed the checker, added the checker reagent to the ref solution, tested again but the result came out at 5,7dKh...? I am sure I must have done something wrong here..
Many thanks and kind regards.
