Review: accuracy that doesn't break the bank - Great tool. reads accurately. easy to calibrate. Comes with a great protective case that keeps it safe while not in use, as well as a small screwdriver for calibration and a dropper for your samples. My only criticism would be that it's a little too dark. I have to hold the glass pretty much right to a light source to see it really clearly but if you stand next to an open window during the day you'll be good. ambient room light at night is not enough and makes what you're viewing dark. Other than that works great! Review: Overall great tool to have for salt water hobby - I was overall happy with the product with minor exceptions. The first thing I noticed is when I came it looked as if it was used versus being new. There also was no instructions at all. Luckily I was able to figure out how to use it via YouTube. A great thing was it was already calibrated pretty close to accurate and it was very simple to use. ## Features - Measures on 2 Scales: Aquariums refractometer features Specific Gravity (D 20/20) 1.000-1.070sg and parts per thousand 0-100PPT (1‰=1ppt=1000ppm) - Seawater refractometer measures saltwater or salinity of water, ideal for aquarium, marine monitoring, fish-keeping,salty pools&spas and etc. - ATC Function: salty water refractometer with automatic temperature compensation, allow you obtain accurate readings easier and faster - Salinity Refractometer is made of aluminum body and ABS rubber light and very sturdy, comes with a hard plastic case, a mini screwdriver, a dropper - Easy to Use: put 2-3 drops on the saltwater’s prism, towards light then to get the accurate readings through the optic eyepiece, ideal for replacement the poor quality and difficult to read hydrometer refractometer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZHZY2J1 | | ASIN | B07ZHZY2J1 | | Additional Features | Lightweight, Portable | | Age Range Description | Adult pets | | Best Sellers Rank | #230,867 in Pet Supplies ( See Top 100 in Pet Supplies ) #42 in Aquarium Hydrometers #3,968 in Pool Chemicals & Water Testing Products | | Brand Name | RZ Mask | | Breed Recommendation | Small, Medium Breeds | | Color | black and silver | | Customer Reviews | 4.6 4.6 out of 5 stars (773) | | Date First Available | November 14, 2019 | | Dog Breed Size | Medium | | Indoor Outdoor Usage | Indoor | | Item Dimensions L x W x H | 3.97"L x 5.24"W x 1.07"H | | Item Shape | Rectangular | | Manufacturer | RZ | | Manufacturer | RZ | | Material Type | Aluminum, Plastic, Rubber | | Pattern | saltwater tester | | Pet Toy Type | Chew Toy | | Product Dimensions | 3.97 x 5.24 x 1.07 inches; 9.17 ounces | | Product Style | Utilitarian | | Recommended Uses For Product | water | | Subject Character | Fish | | Target Species | Fish | | Theme | Marine Life | | UPC | 799418089683 | | Unit Count | 1.00 Count | | Water Resistance Level | Not Water Resistant | ## Images ![Salinity Refractometer - Image 1](https://m.media-amazon.com/images/I/61+iqLr-knL.jpg) ![Salinity Refractometer - Image 2](https://m.media-amazon.com/images/I/61IGU+0Az-L.jpg) ![Salinity Refractometer - Image 3](https://m.media-amazon.com/images/I/612NVJK8JWL.jpg) ![Salinity Refractometer - Image 4](https://m.media-amazon.com/images/I/71f71h1fohL.jpg) ![Salinity Refractometer - Image 5](https://m.media-amazon.com/images/I/71XN0i-cYwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ accuracy that doesn't break the bank *by R***Z on June 25, 2020* Great tool. reads accurately. easy to calibrate.

It's treated me well, no problems since I bought it. It's been very reliable and accurate with salinity levels, durable and easy to clean. Love how it came in the hard protective box, helps to keep it protected. If i had to rebuy another refractometer, I would go with this one again. --- ## 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.pt/products/167489394-salinity-refractometer](https://www.desertcart.pt/products/167489394-salinity-refractometer) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-25*
