This item's descriptive data is currently all messed up. I reported it to Amazon several days ago and it remains a disaster. This item is supposed to be a Taylor R-0004 reagent in the 2 oz size (a.k.a. R-0004-C). There is no "2.75 oz" size available and this is NOT a DPD reagent. it is a pH Reagent. **Q: Can this be used to test drinking water?** A: This reagent is for use with a Taylor test kit, such as the K-2006 FAS-DPD chlorine test kit. If you have one of those, or at least the pH comparator tube (the one with the colored windows to compare the color of the test water to), then yes, you can then use this reagent to find the pH of drinking water (if it's between 7.0-8.0). If the test water is out of this range, then no.When used with the Taylor K-2006, you can measure the pH in 0.2 increments (from pH 7.0-8.0). **Q: how many drops per 10 ml ?** A: Hi 5drops per 44ml **Q: Can you tell me the expiration date** A: 04/17 ## Frequently Bought Together - Taylor Technologies R-0004 pH Indicator Reagent, 2 Ounce - Taylor R-0008-C, Total Alkalinity Indicator, 2 Ounce, For Testing Total Alkalinity Levels in Pool and Spas, Dropper Refill for Water Test Kits, Replace Annually | Made in the USA - Taylor Technologies R-0871-C Fas-Dpd Titrating 2 Oz --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/80870628-taylor-r0004c-reagent-ph-indicator-solution-4-2-oz-r](https://www.desertcart.jp/products/80870628-taylor-r0004c-reagent-ph-indicator-solution-4-2-oz-r) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-29*
