Three Hanna instruments in one case for comparing honey batches: a digital refractometer, a conductivity meter and a colour photometer.
The kit brings together routine honey-room checks and the technical documentation needed to carry them out. It helps track differences between harvests and organise batches before packing or sending samples to a laboratory. Each instrument measures a different property and requires its own sample preparation.
01 · REFRACTOMETRY
The HI96801 reports °Brix. Measure a homogeneous sample, free of crystals and bubbles and equilibrated to the instrument’s temperature. In the attached “Honey moisture at 20 °C” table (PDF in Spanish), 78.4 °Brix is approximately 20.0% water and 80.3 °Brix is 18.0%. At these two points, subtracting Brix from 100 overestimates water by 1.6–1.7 percentage points and can cause unnecessary rejection or drying of a batch. As a practical storage target, aim for moisture below 18%. In Spain, Royal Decree 1049/2003 sets a general maximum of 20%, or 23% for heather honey from Calluna; baker’s honey has separate limits.
02 · CONDUCTIVITY
Prepare the IHC solution using 20 g of honey dry matter in a final volume of 100 ml. For honey at 18% water, weigh 24.39 g and make up to 100 ml with distilled water. The method’s reference is 20 °C: confirm the conductivity meter’s temperature reference before comparing results. Spain’s RD 1049/2003 specifies up to 0.8 mS/cm for blossom honeys and at least 0.8 mS/cm for honeydew honey, chestnut honey and their blends. 0.8 mS/cm equals 800 µS/cm. Exceptions are strawberry tree (Arbutus), heathers (Erica), eucalyptus, lime (Tilia), ling heather (Calluna), manuka (Leptospermum) and tea tree (Melaleuca).
03 · COLOUR
The photometer reports colour in mm Pfund and uses glycerol as its reference. Use clean cuvettes and clear samples to compare batches consistently. Floral-origin assessment combines colour, conductivity, sensory profile and pollen analysis with the apiary’s flowering context.
04 · BEFORE BUYING
Choose it when you use all three measurements and keep batch records. Record date, sample, temperature, instrument and result. Plan for standards and consumables, deionised water, a balance and volumetric glassware for conductivity preparation.
