If I have the TF 100 is there any reason to switch to the Taylor K-2106 ? It’s less expensive, right? But will do as good a job of it or similar?
Have you been using the TF100 for testing bromine? I’m out of my depth now and didn’t know it the TF100 0r K2006 could be used for bromine.
What sample size did you use for the test, 25mL or 10mL?
If 10mL samples size is used, the the titration reports as 1.25ppm bromine per drop. If the 25mL sample size is used, then the titration reports as 0.5ppm bromine per drop.
Match up colour? I’m definitely out of my depth, I thought the TF100 has a FAS-DPD titration test for FC, pink to clear where one drop = 0.5ppm for a 10ml sample. Maybe we could ask @JoyfulNoise for some help.
Move on to the FAS-DPD test.
Using a 10ml or 25ml pool sample add one scoop of R-870, swirl. Add R-871 drop wise while swirling and counting drops till the pink turns clear. For bromine in a 10ml sample 1 drop = 1.25ppm(Total Br), or for a 25ml sample 1 drop = 0.5ppm(Total Br).
