How can I repair an old, rusty hinges refractometer?

[WhalesLovePineapple]

I have this refractometer that's over 5 years old. Since then, the hinges has rusted and it no longer is as flexible as it used to be. However, I still used it anyways and my reef tank seems to be doing alright.

Is there a way to repair it to its former glory or should I just buy a new one?

Try WD40 then give it a good cleaning afterwards what’s the worst that can happen buy a new one worth a shot I think

Just had this same problem. been away for about 6 yrs. got old stuff out. cover would not move.
Mine had a screw on each side that acted as the hinge. put a drop of oil on screws and removed, cleaned up screws and inside cover area.
Put back together, re calibrated and works great.

Take a look in the “articles”

There in an article about keeping your refractometer in shape.

I just came from that article - https://www.reef2reef.com/threads/lubricate-your-refractometer.444486/
I understood that WD40 would help with the hinges, but with the unit itself I was wondering after all these years it can still be used with a recalibration fluid? ANy recommendations for the recalibration fluid?

What did you use to recalibrate?

You can buy a small bottle of calibration fluid.

I calibrate before every use
