Taylor Bromine Complete Test Kit K-2106 — FAS-DPD Titration Pool & Spa Water Test Kit (Compact Case, Multi-parameter)

The Taylor K-2106 FAS-DPD Bromine Complete Test Kit is a precision titration kit for accurately measuring bromine, pH, alkalinity, calcium hardness, and acid/base demand in pools and spas.

This compact, all-in-one kit supplies the specific reagents and tools needed to perform professional-style water chemistry tests at home or on-site. Taylor has supplied water testing solutions for decades, and the K-2106 is built for repeatable, laboratory-like titrations using FAS-DPD chemistry for bromine and DPD for chlorine comparisons. The kit's graduated cylinder includes a measurement chart to speed testing and reduce guesswork.

How does the K-2106 measure bromine accurately?

The kit uses FAS-DPD titration, a widely accepted method to quantify combined bromine and free halogen levels precisely. The FAS-DPD reagent reacts with the DPD indicator until the sample loses its pink color, indicating the endpoint for titration.

• Includes FAS-DPD titrating reagent (A size) for bromine titration.
• DPD powder (I size) changes color to show free halogen presence.
• Titration yields numerical ppm results rather than relying on visual comparators alone.
• Graduated cylinder with printed chart simplifies volume-to-ppm conversion.

What other water parameters can I test with this kit?

Beyond bromine, the K-2106 measures pH, total alkalinity, calcium hardness, plus acid and base demand to help balance pool or spa chemistry. Each parameter uses dedicated reagents included in the kit to produce reliable, repeatable readings.

• pH Indicator Solution (Phenol Red) for pH measurement.
• Total Alkalinity indicator and thiosulfate for accurate alkalinity readings.
• Calcium buffer, calcium indicator liquid, and hardness reagent for calcium hardness tests.
• Acid demand and base demand reagents to determine how much chemical adjustment is required.

How easy is the K-2106 to use for routine pool care?

The kit is designed for straightforward step-by-step testing: draw a sample into the graduated cylinder, add the specified reagents, and perform titrations or color comparisons according to the instructions. Results are fast and precise, making it suitable for routine weekly checks or troubleshooting water issues.

• Comes with clear instructions for each test included in the kit.
• .75 ounce reagent bottles are sized for many tests without frequent repurchasing.
• Graduated cylinder includes an on-cylinder measurement chart to simplify reading.
• Compact case stores reagents and tools for easy transport and field testing.

What supplies are included and when will I need replacements?

The K-2106 ships with all reagents required to perform the listed tests and includes the essential titration chemicals in calibrated volumes. Frequency of replacement depends on how often you test; most hobby pool owners will find the reagent sizes last several months with routine use.

• Included reagents: pH indicator, acid/base demand reagents, thiosulfate N/10, alkalinity indicator, sulfuric acid .12N, calcium buffer and indicators, hardness reagent, DPD powder I, and FAS-DPD reagent.
• Reagent bottles are .75 oz (A size) for most titrations; powder DPD is I size.
• Replace reagents if past expiration or if color shifts indicate degradation.

Who is this for: The Taylor K-2106 Complete FAS-DPD Bromine Test Kit is ideal for homeowners, pool service pros, and spa managers who want laboratory-style titration accuracy without sending samples out. It fits users who prefer precise, numerical results for bromine and the core balancing parameters—especially where combined disinfectant control and correct calcium and alkalinity levels matter for water clarity and equipment longevity.
