TAYLOR 2OZ #2 DPD REAGENT
Product Overview
Formulated for clean color development, this secondary reagent gives pool operators a repeatable readout when measuring free chlorine.
Paired with DPD #1, Taylor R-0002-C serves as the color indicator to measure active sanitizer levels in residential and commercial pools. Packaged in a 2 oz (60 mL) dropper bottle, this R-0002 replacement delivers controlled drop volumes to prevent over-titration and distorted color bands. The 2OZ size supplies roughly 1,000 drops, keeping service kits stocked through heavy testing cycles.

Benefits & What Makes It Different
Calibrated Dropper Tip
Dispenses uniform 0.05 mL drops so your sample volume and dye concentration stay exactly proportional.
2 oz Refill Volume
The 60 mL (2OZ) supply fits standard service kit cases while providing approximately 200 standard five-drop chlorine tests.
Controlled Indicator Chemistry
Reacts instantly with R-0001 to show free chlorine without drifting into false-positive combined chlorine readings.
Product Details
N,N-Diethyl-1,4-phenylenediamine sulfate (<1%)
Add 5 drops to a 9 mL pool sample alongside 5 drops of R-0001 according to test kit comparator instructions.

When To Use This
Pro Tip
Hold the dropper bottle strictly vertical—never at an angle—and squeeze smoothly without shaking. Angled dispensing changes the drop size by up to 25%, skewing your color comparison block results.
Common Questions & Instructions
What is the difference between Taylor R-0002 and R-0002-C?
The base formula is identical; the suffix indicates package sizing. R-0002 is the chemical catalog number, while the 'C' in R-0002-C designates the 2 oz (60 mL) professional dropper bottle size rather than the standard 0.75 oz residential size.
How long does a bottle of Taylor DPD Reagent #2 last before expiring?
Taylor recommends replacing liquid reagents annually. Exposure to direct sunlight, ambient moisture, and temperatures above 85°F accelerates oxidation, which causes the liquid to turn amber and produce inaccurate readings.
Why did my sample turn pink then immediately bleach out after adding R-0002?
Extremely high free chlorine levels (typically above 10 ppm) will bleach out the DPD indicator dye instantly, making water look clear even when chlorine is exceptionally high. Diluting the pool sample 1:1 with distilled water verifies if bleaching occurred.
