Joshua. I never bought the TF-100.
I got a kit from Leslie's years ago. The don't sell it anymore. But it is most similar to the K-2005 with some slight differences:
It has a comparator that has a Cl side and a pH side with Yellow and red caps. Both 'cylinders' on the comparator are the same size and are square cylinders rather than circular.
The Cl side goes up to 5ppm and reads shades of pink by adding 5 drops of R-0001 & 5 drops of R-0002. That gives you a FC reading. Then if you want you can add 5 drops of R-0003 to see if it gets even darker pink. That would be your TC reading. Then you do the math TC - FC to get your CC (Meh. as far as accuracy). All three of those indicators/reagents came with my kit.
The pH side takes 5 drops of R-0014 (very similar to R-0004 but weaker and only works with my comparator) and reads up to 8.2. This is more than sufficient of a test.
Kit also came with R-0015 & R-0016 which is the acid demand and base demand test, respectively. I rarely used them. Actually I don't think I ever have unscrewed the cap of the base demand (Low pH never an issue for me).
Here's a pic of my comparator:
Other contents of the kit:
R-0007, 8, & 9 for TA with a cylinder with bunch of ml markings on it. But the 25ml mark is the only one to use as per the instructions
R-0010, 11, & 12 for Calcium hardness (use same cylinder as the TA one)
For CYA - A small plastic bottle with 7ml and 14ml markings on it, the test tube with the black dot, and the CYA solution of course.
So that's your long winded answer to why I have the reagents already. Now with this new 2000 series comparator I just purchased yesterday on Amazon. The pH uses R-0004. Well I actually have that too. Reason being, last year I was running low on R-0014. So I went on Amazon to buy a replacement. I saw the larger (2oz) vial of "Phenol Red" and bought it. What I didn't realize is that I bought was indeed R-0004. So I have had this extra 2 oz tube with the wrong comparator. Now once the 2000 series arrives in the mail I will be able to use this solution finally.
