I’m not sure anyone would use it for temp... there are much easier ways to take the temperature of your tank, so I’m not worried about temp accuracy at all. And .001 for SG seems pretty good to me. Frankly even on my cheap refractometer I’m not sure I can get much better accuracy than that. The line isn’t defined enough to get closer than about .001 anyway.
It’s a luxury for sure, but it’s certainly accurate enough for my needs and much easier than reading a standard refractometer.
