Bad Refractometer - Advice Required...
As I start reviewing my equipment, I noticed that I haven't been investing much in my Refractometer.
I have 2 refractometers, on both occassions, I bought them from eBay (China), so quality is questionable.
I talked to my LFS and he said there is no need to purchase to expensive Milwaukee or Hanna branded one ... just come in and he'll calibrate it for me.
In saying that, I don't think my one is calibrate-able ... so the story is (from day 1 since I got it):
Is this one doomed? no good? what/which one should I purchase? If I fork out $$$ for good ATC refractometer, it doesn't guarantee that I'm not getting a bad batch, am i?

- Used RODI water and calibrate it to 0 SG.
- The next day, when I used RODI water and I'm expecting 0 SG, it goes off 0 SG ...
- So, I calibrate it again to 0 SG.
- The next day, it went off again ... ... like WTH ...
