Most accurate Refractometer?

[Cassian]

I have an ATC but I think it needs to be recalibrated. I haven't recalibrated it sense I got it, but recently read it should be done every month. Is there a better brand of refractometer that is more accurate and doesn't have to be calibrated so often? Its no problem to calibrate it, but this made me question its accuracy.

IME some refractometers hold their calibration longer than others, but if you want to move to a better one then you may want to consider the Milwaukee digital refractometer.
