Taylor R-0002-A DPD Reagent #2 (Pool & Spa Water Testing)

This liquid reagent from Taylor Technologies — part number R-0002-A — is formulated for use with their pool and spa water test kits. It’s used during DPD (diethyl-p-phenylene diamine) tests to measure free chlorine, total chlorine, and bromine levels, helping you maintain safe, balanced water.

Key Features

• DPD-based reagent for accurate free and total chlorine testing (and bromine where applicable).
• Designed for use with Taylor test kits — ensures proper reaction consistency and reliable results.
• Dropper-bottle format allows easy application and precise dosing for water sample tests.
• Suitable for both residential pools and spas — useful for routine water-quality checks and maintenance.

Specifications

• Manufacturer: Taylor Technologies
• Part Number: R-0002-A
• Type: Pool/Spa test reagent (DPD #2)
• Form: Liquid dropper bottle
• Use Case: Combined with other DPD reagents (e.g. R-0001, R-0003) for chlorine or bromine testing

Usage Instructions

Use R-0002-A in the small sample tube (typically 9 mL) when testing for free chlorine or total chlorine. Add the appropriate number of drops according to your Taylor kit’s instructions (often 5 drops after DPD #1), then mix and compare the water color against the kit’s standard chart or comparator block. For total chlorine, follow with DPD #3 reagent as directed. Always test under natural light and ensure clean sampling for best accuracy.

Why It Matters

Maintaining correct chlorine (or bromine) levels is crucial for water sanitation and swimmer safety. Using the correct reagent — such as R-0002-A — ensures that your test results reflect actual sanitizer concentration, helping you adjust dosing correctly and avoid over- or under-treating your pool or spa water.
