FAS-DPD Test

Ah, that's what the codes are all about. All good information! Thanks again to everyone.

I guess I am more than a little dense, but I have searched the site, and I don't know what test kit I need to buy to check free, total and combined chlorine. I apologize, it this the wrong thread, but please direct me to the right one. Thanks, Webfeet

For a complete test kit that includes the FAS-DPD chlorine test for free and combined chlorine (the sum of free and combined is total chlorine), that's the Taylor K-2006 test kit. This will also test pH, Total Alkalinity (TA), Calcium Hardness (CH) and Cyanuric Acid (CYA). It also includes an acid/base demand test, though that's not particularly useful for small increments in pH.

If you only need the chlorine test kit because you have everything else, then you can get the Taylor K-1515-A which is a FAS-DPD chlorine test only (no tests for pH, TA, CH or CYA).

You can get the equivalents at Leslies On-line. The full test kit is the FAS-DPD Chlorine Service Test Kit but you can also get just the FAS-DPD test. They both use Taylor reagents and equipment (vials and cells) in a Leslies box. Just another source.
