Refractometer Repair

[elfloyd]

Checked the calibration on my refractometer... it read a little low so I tried to calibrate. The calibration will only adjust down, and I can't adjust back up.

Anyone have experience repairing refractometers?

I've got one & calibration fluid and coincidentally, no tank! $20?

Seems like the prism head may be detached from the calibration screw.

JeF4y... not saying I'm ready to throw in the towel... but where in Atlanta are you?
