Buy SunGrow Aquarium Refractometer, 7.6 Inches, Measure Salinity of Water, Remarkable Accuracy, Includes Calibration Tool, Ensures Overall Health of Plant and Marine Life, Easy and Clear Reading at desertcart UK. ## Features - Specifically Designed Refractometer For Saltwater Aquarium --- The algorithm is made specifically for testing seawater and saltwater. This is different from a standard refractometer which is not calibrated to check salinity of aquarium water and will give an error in your readings. - Automatic Temperature Calibration --- The calibration process should be carried out with both the room and the instrument at 68° F. The refractive index of a liquid changes with temperature. Due to the automatic temperature calibration, any changes in ambient temperature from 50° F- 86° F will not affect the accuracy of the reading. - Easy And Clear Reading For Saltwater Aquariums And Reef Tanks --- The refractometer comes with a focus adjustment on the eyepiece, this will give you clarity of the optics and a sharp line for easy reading. - Comes In A Solid Case Includes Pipette And Calibration Tool --- This refractometer is not only built extremely well, but it comes with a durable hard case for easy storage of the refractometer when not in use. It also includes a calibration tool and a pipette. - Keep Your Fish And Plant Life In Optimal Well-being --- Pure saltwater is crucial for the vitality of your marine or reef aquarium. Use this refractometer to measure the salinity of the water, the target level of salinity in a reef tank should be 35 ppt. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071RMR7BJ | | Batteries Included | No | | Batteries required | Yes | | Best Sellers Rank | 55,998 in Pet Supplies ( See Top 100 in Pet Supplies ) 10 in Aquarium Hydrometers 893 in Aquarium Filter Accessories | | Customer Reviews | 4.6 4.6 out of 5 stars (553) | | Date First Available | 26 April 2017 | | Item Weight | 20 g | | Manufacturer reference | ZJSJRJ | | Number of Items | 1 | | Package Dimensions | 20.5 x 8.5 x 5.4 cm; 20 g | | Quantity | 1 | ## Images ![Aquarium Refractometer, 7.6 Inches, Measure Salinity of Water, Remarkable Accuracy, Includes Calibration Tool, Ensures Overall Health of Plant and Marine Life, Easy and Clear Reading - Image 1](https://m.media-amazon.com/images/I/71DvAhisavL.jpg) --- ## 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.vu/products/86260533-aquarium-refractometer-7-6-inches-measure-salinity-of-water-remarkable](https://www.desertcart.vu/products/86260533-aquarium-refractometer-7-6-inches-measure-salinity-of-water-remarkable) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-09*
