I bought my refractometer several years ago and have forgotten what model it is. It is either the RHS-10 or RHS-10ATC. It is one of the old generic blue chinese refractometers. I can see no model markings on the case or instrument. Any ideas on how to identify this thing?

If it works and calibrates, what does it matter? Just call it the OGBCR meter.

Because an ATC refractometer compensates for temperature one it is calibrated. A non ATCdoes not and can throw off your reading. I don't want to calibrate every time I use it. Being the person that I am, I more than likely bought the ATC version, but it would be nice to be certain.
