Plastic refill bottle contains 8oz. Review: Perfect quantity to refill test bottles. - The Blue Devil - Phenol Red arrived quickly and perfectly packed. The hardest part was breaking through (and removing) the top seal to open it! It was well sealed. I used some of the contents to test pool water immediately after it arrived and compared the results to the last of my "old phenol red". Same results hence I expect the product quality is precisely the same as previous purchases, BUT it is 1/3 the price! I am very happy, Thanks Review: It’s Red. - Only takes 2 drops to do the test in my twin tube tester. (Comparing color with a new bottle of another brand). this bottle will last us 50 years but is a much better value than buying just 2 of those 3/4 ounce bottles ## Features - Tests Pool'S Ph Indicator - 8 Oz Plastic Bottle - Reagent Refill For Blue Devil Test Kits - No Assembly Required ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DP5CSKW | | Best Sellers Rank | #186,765 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #217 in Swimming Pool Water Test Kits | | Brand | Blue Devil | | Brand Name | Blue Devil | | Customer Reviews | 4.5 out of 5 stars 103 Reviews | | Global Trade Identification Number | 00054629174925 | | Manufacturer | Valterra Products, LLC | | Material Type | Plastic | | Model Number | B7492 | | Part Number | B7492 | | Ph Range | 7.2-7.6 | | Recommended Uses For Product | Swimming Pool, pH Test | | Sterility Rating | 7.2-7.6 | | UPC | 054629174925 | ## Product Details - **Brand:** Valterra - **Ph Range:** 7.2-7.6 - **Recommended Uses For Product:** Swimming Pool, pH Test - **Manufacturer:** Valterra Products, LLC - **UPC:** 054629174925 ## Images ![Blue Devil B7492 #2 Phenol Red (5-Way), 8 oz Bottle - Image 1](https://m.media-amazon.com/images/I/71UXAb20rdL.jpg) ## Questions & Answers **Q: What is the % concentration of this solution (assume this is listed on the label). Not asking about drops, but about % solution of this product.** A: Can't tell you the specific percent concentration, but it is about 1/3 to 1/2 the strength of the Taylor R-0004 pool pH test solution. (need twice as many drops). **Q: Is this equivalent to taylor R-0004 or R-0014?** A: The Blue Devil B7492 #2 Phenol Red is equivalent to Taylor R-0004. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect quantity to refill test bottles. *by M***E on December 22, 2024* The Blue Devil - Phenol Red arrived quickly and perfectly packed. The hardest part was breaking through (and removing) the top seal to open it! It was well sealed. I used some of the contents to test pool water immediately after it arrived and compared the results to the last of my "old phenol red". Same results hence I expect the product quality is precisely the same as previous purchases, BUT it is 1/3 the price! I am very happy, Thanks ### ⭐⭐⭐⭐⭐ It’s Red. *by W***Z on July 26, 2022* Only takes 2 drops to do the test in my twin tube tester. (Comparing color with a new bottle of another brand). this bottle will last us 50 years but is a much better value than buying just 2 of those 3/4 ounce bottles ### ⭐⭐⭐⭐⭐ Use ~3 drops for twin Poolmaster chlorine/PH tester tube *by A***K on May 16, 2023* I bought this to replace the PH dropper that came with my Poolmaster twin chlorine/PH tester which required 5 drops of their included 3/4oz bottle. The red color in this product/brand is a "richer" red, and when I compared to my existing PH red dropper results, I needed to only use about 3 drops of this solution to get the comparable result. If I used 5 drops of this solution it was off the charts high...too red. Note, another user recently reported a similar (only 2 drops needed) as well. ## Frequently Bought Together - Blue Devil B7492 #2 Phenol Red (5-Way), 8 oz Bottle - Pentair R161046 No.1 OTO Solution, 8-Ounce --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.eg/products/18904770-blue-devil-b7492-2-phenol-red-5-way-8-oz](https://www.desertcart.com.eg/products/18904770-blue-devil-b7492-2-phenol-red-5-way-8-oz) --- *Product available on Desertcart Egypt* *Store origin: EG* *Last updated: 2026-08-14*
