It offers precise phosphate measurement essential for maintaining coral health in reef tanks, featuring a compact, portable design and an intuitive interface. Ideal for aquarium professionals and marine biologists, it comes complete with a starter kit and a 1-year warranty. ## Description The HI774 is a cost-effective way to measure phosphate in marine systems, including reef tanks. Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank's water chemistry to help ensure long-term coral health. Phosphates are one of the many forms of phosphorus compounds found in marine waters. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth in your reef tank. This can become problematic because algae often outcompetes sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef. ## Features - Hanna HI774 : Low Range Phosphate Tester is designed for direct measurement - Compact Design : With its compact and portable design, this meter is perfect for on-the-go testing in various applications. - MULTI USE : Ideal for aquariums and marine biology applications. - Portable : handheld colorimeter goes where you go. - Easy Operation : Features a user-friendly interface with simple button operation, making it easy to navigate and take measurements. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D7N8H2LP | | ASIN | B0D7N8H2LP | | Age Range Description | Adult | | Best Sellers Rank | #32,688 in Pet Supplies ( See Top 100 in Pet Supplies ) #53 in Aquarium Test Kits | | Brand Name | WLR Industries | | Color | Green | | Customer Reviews | 4.7 4.7 out of 5 stars (135) | | Date First Available | June 11, 2021 | | Date First Available | June 11, 2021 | | Directions | Use as directed | | Included Components | cuvettes with caps, starter kit, battery, instructions | | Item Package Dimensions L x W x H | 7.56 x 4.88 x 2.8 inches | | Item Weight | 0.29 g | | Item model number | 774 | | Item model number | 774 | | Manufacturer | WLR Industries | | Manufacturer | WLR Industries | | Model Name | Hanna HI774 | | Package Dimensions | 7.56 x 4.88 x 2.8 inches; 0.01 ounces | | Specific Uses for Product | Water Aquarium checker tester | | Target Audience Keyword | Fish | | Warranty Description | 1 year manufacturer warranty | ## Images ![WLR Industries Hanna HI774 Phosphate Ultra Low Range Colorimeter for Marine and Saltwater appllications Phosphate Checker - Image 1](https://m.media-amazon.com/images/I/41Ti7GycM9L.jpg) ![WLR Industries Hanna HI774 Phosphate Ultra Low Range Colorimeter for Marine and Saltwater appllications Phosphate Checker - Image 2](https://m.media-amazon.com/images/I/21lwMDIJTvL.jpg) ![WLR Industries Hanna HI774 Phosphate Ultra Low Range Colorimeter for Marine and Saltwater appllications Phosphate Checker - Image 3](https://m.media-amazon.com/images/I/61wcsSL1nqL.jpg) ![WLR Industries Hanna HI774 Phosphate Ultra Low Range Colorimeter for Marine and Saltwater appllications Phosphate Checker - Image 4](https://m.media-amazon.com/images/I/21Ibc7QSfPL.jpg) ## Frequently Bought Together - WLR Industries Hanna HI774 Phosphate Ultra Low Range Colorimeter for Marine and Saltwater appllications Phosphate checker - Hanna Instruments High Range Nitrate Checker HI782 - WLR Industries Hanna HI772 checker Saltwater Aquarium Alkalinity Colorimeter Checker Tester --- ## 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.sn/products/640928908-wlr-industries-hanna-hi774-phosphate-ultra-low-range-colorimeter-marine](https://www.desertcart.sn/products/640928908-wlr-industries-hanna-hi774-phosphate-ultra-low-range-colorimeter-marine) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-12*
