Notice: 1.Actual color may be slightly different from the image due to different light effect 2.Please allow 1-3cm deviation due to manual measurement Description: Measuring Range: 020 Minimum Scale: 0.2 Automatic Temperature Compensation: 1030 DegreeC Length: 17cm / 6.7inch Weight: approx. 219g Instruction: 1. Open the cover and carefully wipe the prism with a soft cloth. 2. Take a few drops of the solution to be measured, place on the detection prism, gently close the cover to avoid producing bubbles which will make the solution spread all over the prism cover. 3. Put the cover directly point to the light source or bright place, observe the field of view through the eyepiece. 4. Turn the eyepiece to adjust the hand wheel to make the blue and white line clear. The scale value of the dividing line is the concentration of the solution. Package List: 1x Handheld Brix-Refractometer for Testing
