Refractometers?

Ive got a ZGRS-10ATC refractometer. It has it's own built in light so you can use it even when the lights are out.

I've had it for about 4 years with no problems and it works a lot better than my old swing arm or floating hydrometer.

That's the same one that Drs Foster and Smith sell for $45 and the one we bought.

 

Be sure to spend about $5 more and buy the standard solution to check calibration regardless of the refractometer you get:

The biggest thing is you want to make sure that it has ATC. There are folks here that have the ebay ones that seem to work just fine and the Dr. Foster and Smith one is very popular too. That is the one I have and it seems to work very well.

I want to ditch my old swing arm Hydrometer and get a Refractometer. Brands? Models?

That misco digital refractometer is nice...but...it better be for $435! I think I will stick with my $50 Dr. F&S unit.
