The reading resolution is 1 ppt. It is designed for the measurement of seawater (marine aquaria) or very low concentrated salt solutions. The second scale is for reading of the salt solution density in range 1.000 to 1.070 g/cm3 (resolution 0.001 g/cm3). The usual salinity of the selected aqueous solutions 1.Fresh water --- 50 ppt (Salinity 36 ppt means, that there are 36 grams of salt in 1 liter aqueous solution.) Measurement: The liquid measurement is very easy. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look throught the eyepiece against the light (focus, if necessary) and you will be able to read the result value on the scale.

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 ### ⭐⭐⭐⭐⭐ Perfetto *by E***E on 3 April 2026* Ottimo ### ⭐⭐⭐⭐⭐ Salinity tester *by R***E on 8 January 2026* ### ⭐⭐⭐⭐⭐ Good *by A***Y on 6 March 2026* ## Frequently Bought Together - Salinity Refractometer for Seawater and Marine Fishkeeping Aquarium 0-100 PPT with Automatic Temperature Compensation - 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/255888433-salinity-refractometer-for-seawater-and-marine-fishkeeping-aquarium-0-100](https://www.desertcart.vu/products/255888433-salinity-refractometer-for-seawater-and-marine-fishkeeping-aquarium-0-100) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-13*
