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 . 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% / 0 to 80C (32 to 176F) Resolution: 0.1% / 0.1C (0.1F) Accuracy: 0.2 % / 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 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.
