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.

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.

Quick and easy salt test
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.

Great and accurate
Very easy to use and way more accurate than a hydrometer.

Works well. Must calibrate.
Works well for a reef tank, but you must calibrate with calibration solution (35 ppt). I let the solution come to a similar temperature as my tank. I recommend calibrating before each use.

Easy to use
Comes with 2 droppers and a screwdriver to calibrate it with. Worth the money

Excellent Salinity Refractometer – Accurate, Durable, and Easy to Use
This is a great product! The readings are accurate and very easy to read, even for beginners. The instructions included were clear and helpful, making setup and calibration simple. It also comes with a strong, protective case that keeps the refractometer safe when not in use — a really nice touch for long-term durability. Absolutely no complaints here. Highly recommend for anyone working with seawater or saltwater aquariums.
