I have a question about the CH test in the TF100 test kit. When testing my CH the solution starts to turn blue with many red specs at about 140, the solution does not turn COMPLETELY blue with no red specs until about 250. My assumption is that the 250 is the correct reading. Am I correct?
Question about CH test
- Thread starter radiation
- Start date
Most likely metal ion interference. Add 5 drops of the last reagent first and then do the test normally. Count the 5 drops in the total number of drops.
