Benefits & What Makes It Different
Prevents Bleach-Out
Unlike liquid DPD reagents that bleach clear above 10 ppm, this powder measures free chlorine accurately past 20 ppm.
Standard 10 g Packaging
Contains enough reagent for approximately 150 to 200 individual FAS-DPD sanitizer tests on standard residential routes.
Precise Endpoint Indicator
Turns pink in the presence of free chlorine and drops cleanly to crystal clear at the final titrant drop.
Product Details

2 level scoops (using Taylor .05g dipper spoon) per 10 mL or 25 mL sample
Compatibility
- Taylor K-2006 and K-2006C Test Kits
- Taylor R-0871 FAS-DPD Titrating Reagent
- Residential and commercial chlorine water testing
When To Use This
Pro Tip
Keep the sample vial completely dry on the outside before scooping; even a micro-drop of water on the dipper spoon handle can contaminate the entire 10 g bottle and cause premature oxidation.
Common Questions & Instructions
What is Taylor R-0870 DPD powder used for in pool water testing?
Taylor R-0870 is the primary indicator powder for FAS-DPD chlorine test kits like the Taylor K-2006. Adding two level scoops reacts with free chlorine in a 10 mL or 25 mL water sample, turning it pink prior to titration.
Why has my Taylor DPD powder turned grey or brown?
DPD powder oxidizes when exposed to moisture and air over time, causing it to darken. While slightly off-white powder may still function, dark grey or clumping powder will cause inaccurate readings and should be replaced.
How often should I replace the 10 g bottle of R-0870 DPD Powder?
Taylor recommends replacing testing reagents after one year or at the start of each new testing season to ensure chemical accuracy and crisp color transitions.
