Review: Simple to use and more than accurate enough for my needs - I have a very simple task: distinguish between fresh and saltwater in the bilges of boats without tasting. This instrument is very effective for that purpose, requires no batteries, is easy to read, and is very reliable. I only need to distinguish values near 0 from values near 35 ppt, so can’t speak for how well it would work for more demanding applications, but it works for me. ## Features - Measure salt water or salinity of water, ideal for aquariums and marine monitoring. - Measures on 2 scales, Specific Gravity (D 20/20) and parts per thousand. - Features automatic temperature compensation. - Comes with hard case, dropper, screwdriver, user manual and cleaning cloth. - The main part is made of chromium, it's very durable. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B018LRO1SU | | Best Sellers Rank | #6,080 in Pet Supplies ( See Top 100 in Pet Supplies ) #1 in Aquarium Hydrometers #9 in Aquarium Test Kits | | Brand | Agriculture Solutions | | Brand Name | Agriculture Solutions | | Customer Reviews | 4.6 out of 5 stars 4,846 Reviews | | Item Weight | 8.8 ounces | | Manufacturer | Xin Da Cheng | | Manufacturer Part Number | WL0020-ATC | | Model Number | WL0020-ATC | | Pet Type | Fish | | Target Species | Fish | | UPC | 710824285742 | | Unit Count | 1 Count | ## Product Details - **Brand:** Agriculture Solutions - **Item Weight:** 8.8 ounces - **Manufacturer:** Xin Da Cheng - **Pet Type:** Fish - **Unit Count:** 1 Count ## Images ![Salinity Refractometer for Seawater and Marine Fishkeeping Aquarium 0-100 PPT with Automatic Temperature Compensation - Image 1](https://m.media-amazon.com/images/I/81equeUKnXL.jpg) ## Questions & Answers **Q: Is this any use for hydroponics?** A: It is used for testing the salt water fish tank. **Q: I want to test the brackish canal water to see if i can use it for irrigation. will this tester work? I was told to check the salinity of the canal** A: Yes, brackish water ranges between 0. 05 to 30 PPT **Q: What does this come with** A: All you get is the refractometer, case and a small screwdriver for adjusting it. Unless they have added something since we bought ours about a year ago. It will not let me post a picture or I would. **Q: Hi, i bought a calibrating fluid and calibrated my refractometer to sg 1.026 but when i test it on distilled water it reads 1.010. why is that?** A: According to R Homes Farleys article this is because this refractometer was made to measure pure salt solutions and they don’t have the exact reflective index of sea water that has some additional elements. Therefore calibrating with a solution that matches the reflectivity of seawater at 35ppt is needed and once done it will not measure distilled or Rodi water accurately. But you will have a more accurate measurement for your salt water aquarium. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Must have *by D***L on January 3, 2026* I’ve been using the Agriculture Solutions Salinity Refractometer for my saltwater fish tank, and it has made maintaining proper salinity levels incredibly easy.
