I just bought a refractometer off of your website, and successfully calibrated it using purified bottled water. It was about .005 off, so I decided to recalibrate it. I followed the calibration instructions completely, as I did the 1st time, but it refuses to calibrate. No matter how I turn the calibration screw, the white stays halfway between 0, and the bottom. The instrument has not been dropped or damaged since it was initially calibrated. What could cause this to happen? Also, is there anywhere that I could get some calibration fluid for the refractometer?
