Water in honey |
 |
Wasser im Honig |
| Preview | The moisture content of honey (or conversely the dry matter content) is determined by measuring the refractive index using a refractometer at 20 °C. The refractive index proportionally decreases with increasing water content. Newer refractometers provide a direct reading of the moisture content of the honey sample. To ensure an accurate refractive index measurement, temperature control is required. Most refractometers have automatic temperature compensation; refractometers without temperature compensation come with a reference chart to convert the reading. In this case, it is necessary to take the temperature of the honey sample and use the correction table to get the right value. |
