Calibration fluid incl. syringe
The optimal temperature for measurement is 20º C
19,6% water or 78.8% Brix
The bottle contains 2 ml of clove oil.
Using the syringe, drop 1 to 2 drops of calibration fluid onto the glass, take the crystal stone with the smooth side down and gently rub the oil around. Leave the stone on the glass and then look into the refractometer.
The blue line on the scale should now be at the line at 78.8 Brix / 19.6%. If not, turn the central calibration screw with the provided screwdriver until the lines are on top of each other.
The refractometer is now correctly calibrated. Always wear gloves during calibration.
