Review: Must have - I’ve been using the Agriculture Solutions Salinity Refractometer for my saltwater fish tank, and it has made maintaining proper salinity levels incredibly easy. Accurate salt levels are critical for marine fish and corals, and this refractometer gives consistent, reliable readings every time. The 0–100 PPT range is perfect for seawater and marine aquarium use, and the automatic temperature compensation (ATC) is a huge plus. I don’t have to worry about room temperature affecting the results, which gives me peace of mind that my readings are accurate. Calibration was straightforward, and the results are easy to read and interpret, even for someone who isn’t a professional. Compared to test strips or swing-arm hydrometers, this refractometer is far more precise and dependable. It’s helped me keep my salt levels stable, which has made a noticeable difference in the overall health and behavior of my fish. If you maintain a saltwater aquarium and want a simple, accurate, and reliable tool for monitoring salinity, this refractometer is absolutely worth it. It takes the guesswork out of marine tank maintenance and makes routine checks quick and stress-free.
Review: For the price, it seems to work. - This thing was so inexpensive and it seems to be accurate. Only thing is that it loses calibration quickly. Not sure why. Does the screw come loose just sitting in the case? I just calibrate it quickly with some calibration solution. Kinda annoying, but hey this thing was so inexpensive.

## 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.

### ⭐⭐⭐⭐⭐ Quick and easy salt test
*by J***S on January 1, 2026*

easy to use and I think accurate as I measured out the salt for my tank according to instructions on the salt bag, and when I tested it, it showed exactly what it was supposed to show. I've used it twice now and nothing changed from the first time, so I'm convinced it's great.
