I am contemplating getting a refractometer but not sure which brands are good or bad. There are cheap ones and more costly ones. I have a swing arm hydrometer at the moment, but would like something more accurate. Does anyone have any suggestions? Thanks!

I don't know which ones are very good, BUT I would avoid the RHS-10ATC commonly found on the net and eBay. I bought one and it failed miserably after less than 6 months of normal use.

I am borrowing a friends Sybon at the moment and its pretty decent I guess . . . I can't attest to its long term use though.

I've had the RHS-10ATC for a few months and have had no problems at all, but yea, there's always going to be bad one's. 007, there is a warranty for a year with these refractometers, you should return it and get another for free.

I got the Captive Purity version from Marine Depot and it served me well for almost two years. I ended up giving it to a friend when I thought I was getting out of the hobby. (note to self, there is no getting out :D ).

You could also consider a digital salinity meter, they are easier to read and are also accurate.

I picked up a Sybon refractometer from Premium Aquatics a couple of years ago. Works great and I've never had any problems with it.

How do the digitals work?

Not sure exactly how they work, but here is a link to one.

This is a continuous monitor though.
