(calcium chloride)** A: i don’t see why not…any saltwater could be tested for its saltiness. **Q: where will this be shipped from?** A: Hello. These items will be shipped from US Amazon warehouse. **Q: Is this product accurate enough to test well water for salinity?** A: Yes, this salinity refractometer can measure salt water or salinity of water, ideal for aquariums and marine monitoring. It's accurate. **Q: when calibrating to 0, what counts as distilled or fresh water?** A: After doing some research, apparently you don’t want to calibrate to 0. The reason for the 35ppt calibration fluid is it will lose accuracy the further away you get away from the calibration level. So you want to calibrate as close to the level that you plant to use it at as possible. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by D***G on March 7, 2022* Very easy to use and accurate after I calibrated it. Excellent value. I highly recommend it. ### ⭐⭐⭐⭐⭐ Simply *by M***Y on March 29, 2026* It works! ### ⭐⭐⭐⭐⭐ Great Product *by N***N on July 27, 2026* This appears to be accurate and easy to use. Ocean salinity reads just where it should. No batteries or electronics just an optical lens. A little getting used to looking through a lens, like a telescope but easy enough. Really a good value. ## Frequently Bought Together - Salinity Refractometer for Aquarium Seawater Marine Fishkeeping Salinity Tester 0-100PPT & 1.000-1.070 Salinity Hydrometer Slatwater Refractometer with Automatic Temperature Compensation (ATC) - API SALTWATER MASTER TEST KIT 550-Test Saltwater Aquarium Water Test Kit - Instant Ocean Sea Salt 50 Gallons, For Marine Aquariums, Fast Dissolving --- ## 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.fr/products/293534255-salinity-refractometer-for-aquarium-seawater-marine-fishkeeping](https://www.desertcart.fr/products/293534255-salinity-refractometer-for-aquarium-seawater-marine-fishkeeping) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-10-26*
