The \u003cstrong\u003eTaylor K-2106 FAS-DPD Bromine Complete Test Kit\u003c\/strong\u003e gives you laboratory-grade accuracy at home — no color-matching required for sanitizer readings.

The \u003cstrong\u003eFAS-DPD titration method\u003c\/strong\u003e works differently: you add drops of titrant until the sample turns from pink to \u003cem\u003ecompletely clear\u003c\/em\u003e. That endpoint is unambiguous. Each drop you add equals a precise measurement increment, so your bromine reading is a count — not a color judgment. The result is far more accurate and repeatable, particularly at higher bromine levels where DPD color cards become difficult to read.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's in the Kit\u003c\/h2\u003e\n\u003cp\u003eThe K-2106 includes all reagents needed to run all four tests, packaged in Taylor's 3\/4 oz (22 mL) dropper bottles:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0870\u003c\/strong\u003e — FAS-DPD Powder Reagent (bromine titration indicator)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0871\u003c\/strong\u003e — FAS-DPD Titrating Reagent (bromine titrant)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0004\u003c\/strong\u003e — Phenol Red Indicator Solution (pH)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0005\u003c\/strong\u003e — Acid Demand Reagent (pH adjustment reference)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0006\u003c\/strong\u003e — Base Demand Reagent (pH adjustment reference)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0007\u003c\/strong\u003e — Total Alkalinity Indicator\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0008\u003c\/strong\u003e — Sulfuric Acid Titrating Reagent (alkalinity)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0010\u003c\/strong\u003e — Calcium Hardness Indicator\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-0011L\u003c\/strong\u003e — Calcium Hardness Titrating Reagent\u003c\/li\u003e\n  \u003cli\u003eTaylor 2000-series comparator block, test tubes, and instruction booklet\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow to Use It — The Basics\u003c\/h2\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollect your sample\u003c\/strong\u003e — Draw water from elbow depth (about 18 inches below the surface), away from return jets and skimmers.

Taylor prints lot numbers on each bottle; check the Taylor Technologies website for expiration guidance by lot if needed. Replace any reagent that has changed color, become cloudy, or is past its use-by date — an expired reagent gives a false reading, which is worse than no reading at all.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Pool \u0026amp; Spa Systems\u003c\/h2\u003e\n\u003cp\u003eDesigned specifically for \u003cstrong\u003ebromine-sanitized\u003c\/strong\u003e pools, spas, and hot tubs.

Avoid contact with eyes and skin. Rinse thoroughly with water if contact occurs. Keep out of reach of children. Dispose of spent reagents per local regulations.\u003c\/p\u003e\n\n\u003cp class=\"pro-tip\"\u003e\u003cstrong\u003ePro Tip:\u003c\/strong\u003e Always run your bromine test \u003cem\u003ebefore\u003c\/em\u003e pH. Phenol Red (the pH indicator) can be affected by high sanitizer levels and give a falsely low pH reading. Testing bromine first — and knowing your level is in range — ensures your pH result is reliable.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-24 --\u003e","brand":"Taylor","offers":[{"title":"Default Title","offer_id":53980264235283,"sku":"K-2106-6","price":93.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/taylor-fas-dpd-bromine-complete-pool-spa-test-kit-k-2106-3-4-oz-bottles.webp?v=1777074921","url":"https:\/\/poolaroo.com\/products\/taylorwatertechnologiesllc_k-2106-6","provider":"Poolaroo","version":"1.0","type":"link"}
