REVIEW 2023 - Premium Salinity Refractometer with Automatic Temperature Compensation for Saltwater, Aquarium, Marine Reef Tank Testing - Dual Scale (0-100ppt & 1.000 to 1.070 S.G.)

ONE250 First Impressions

Arrived quickly.

I HIGHLY recommend this to Aquarists! Find a good light source to make reading easier. But with alittle persistance I am able to read it. My corals will be much happier now. I would recommend this product to anyone that has a marine aquarium. It's perfectly accurate based on the known calibration fluid. When I compared it to what my local pet store was reading my water at it was dead on.

ONE250 Final Thoughts

This tool does that.

Compare it with the refractometer and adjust the refractometer so that it matches. On the shaft of the refractometer, there's a little, rubber-covered nub. I bought this refractometer as a more accurate option for salinity than a hydrometer. Be sure to buy the calibration solution and test this before use! Bought this as a back up refractometer. 026 with the new Aquatic Experts fluid. I felt it wasn't accurate which was verified by my LFS.
