Calibration fluid

Calibration Liquid for Honey Refractometer

Calibration liquid is used for possible calibration of the refractometer. The calibration liquid shows a water content of 19.4% solution at 20°C. Therefore, if you want to calibrate the refractometer, calibrate it in a room at 20°C temperature. Apply a drop of calibration liquid to the refractometer prism, the refractometer should show a water content of 19.4%, if it does not show this, gently turn the adjustment screw so that the measured value matches 19.4% water. Content 2ml. Refractometers from our range are already calibrated, so calibration is not necessary.

At refractive index (RI) = 1.488 recalculated to 20°C, according to the commonly used Chataway table for honey, the water content comes out to approximately ≈ 19.4% (approximately 19.3–19.6% depending on rounding and the refractometer manufacturer's table).
Note for beekeeping practice: this applies to data actually related to 20°C (either refractometer with ATC or manual temperature correction).
