FS: Milwaukee digital refractometer

[neeper]

I am selling a Milwaukee digital refractometer. A friend of mine gave me two of these when he shut his tank down. I don't really need two so I am selling one. It's in new-like condition, even has the plastic still on the display. I put a battery in it to test it works and taking the photo. You'll need seawater calibration solution for using it. The model is MA877

Asking $50
