Any recommendations for a great refractometer?

My Digi-Lab TSS digital meter flaked out on me and gave me very inaccurate readings. I don't trust it anymore and I am looking for something more reliable.

Who makes a great device for reading specific gravity?

Thanks for the ideas!

I would recomend a name brand refractometer. Like milwalkee or similar.

Or better yet get conductivity to meausre far more precise.

One issue is that many hobby refractometers do not have a brand name, so it can be hard to give recommendations, but that said, I do not have a specific recommendation. Once you get one, I'd recommend testing/calibration it at least once in a seawater salinity solution, not just RO/DI water. This article has more:
