Digital display honey refractometer, simple rapid determination of three items: honey, sugar content baume degree, moisture. The other can measure the refractive index, high concentration of sugar solution, baume degree, wide application, the measurement precision rapidly. Under normal temperature, the honey baume degree/water content of the relationship between the following 40/23.1, 41/22.3, 41.5/20.2, 42/19.2 and 42/19.2 level honey baume degree should be above 41.6 Range:0 to 90% Brix / 0 to 80C (32 to 176F) Resolution: 0.1% Brix / 0.1C (0.1F) Accuracy: 0.2 % Brix / 0.3C (0.5F) Automatic Temperature Compensation (ATC):between 10 and 40C (50 - 104C) Measurement Time:Approximately 1.5 seconds Minimum Sample Volume:2 metric drops Light Source:Yellow LED Sample Cell:Stainless steel ring and flint glass prism Enclosure Rating:IP65 Battery Type / Life: (1) 9V / 5000 readings(not include) Auto-Off:After 3 minutes of non-use Colour:Yellow Material:plastic Package Contents: 1 * Portable Digital Refractometer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
