For use with Taylor Test Kits. Size: 2 ounce Review: Great value to buy the 2oz size - No one talks about how expensive pool maintenance is, but buying testing chemicals can be one of those "uncharted" expenses. However, Taylor kits are by far the best and most accurate way to measure pool chemistry, and little bottles (3/4 ounce) can be refilled with these 2 ounce bottles for a considerable savings—assuming you go through it fast enough or can store it without the chemicals degrading. Especially valuable if you maintain multiple pools or have multiple test kits that need to be refreshed. Review: The best - Taylor. The best water testing available. Easy to use. ## Features - For use as directed with Taylor Technologies test kits - R-0004 is used for the pH test - Use with 2000 Series Comparator - 2 ounce dropper bottle ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0030EVB74 | | Best Sellers Rank | #3,370 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2 in Analytical Reagents | | Brand | TAYLOR | | Brand Name | TAYLOR | | Customer Reviews | 4.6 out of 5 stars 988 Reviews | | Included Components | swimming-pool-chemicals-and-supplies | | Item Type Name | Taylor Technologies R-0004 pH Indicator Reagent, 2 Ounce | | Item Weight | 2.4 ounces | | Manufacturer | TAYLOR | | Material | solid | | Material Type | solid | | Model Number | R-0004-C | | Part Number | R-0004-C | | Ph Range | 0-14 | | Recommended Uses For Product | Swimming Pool, Spa | | Sterility Rating | 0-14 | | UPC | 840036000199 | ## Product Details - **Brand:** TAYLOR - **Manufacturer:** TAYLOR - **Ph Range:** 0-14 - **Recommended Uses For Product:** Swimming Pool, Spa - **UPC:** 840036000199 ## Images ![Taylor Technologies R-0004 pH Indicator Reagent, 2 Ounce - Image 1](https://m.media-amazon.com/images/I/715OjsrlqML.jpg) ## Questions & Answers **Q: What exactly am i getting here? the model # shows r-0002a with description of 2.75oz while the picture on amazon shows r-0004 with 2oz?** A: Thank you for your question. 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value to buy the 2oz size *by A***T on February 1, 2026* No one talks about how expensive pool maintenance is, but buying testing chemicals can be one of those "uncharted" expenses.
