Specifications:
Item Type: Brick Refractometer
Material: Aluminum alloy, ABS, rubber
Measurement Range: 0-32%
Value:1%
Accuracy: ±1%
How to use:
1. Open the cover and carefully wipe the test prism with a soft cloth. Take a few drops of measuring solution, place it on the test prism, gently close the cover plate to avoid air bubbles, spread the solution to the prism surface. Adjust the fixture to a light source or bright place, observe the field of view through the eyepiece and turn the eyepiece adjustment handle to make the blue and white divided field of vision. Boundary scale value is the concentration of the solution. 0 point calibration is required before calibration and temperature compensation. Take a few drops of distilled water, place it on the detection prism, turn the 0 adjustment screw to align the boundary line to 0% of the scale. Then wipe the detection prism and perform the test. Depending on the model of the equipment, you need to configure a standard solution instead of distilled water during calibration. Another method is (only suitable for measuring sugar content), using the temperature compensation table to get the exact value with the temperature compensation (subtracted) to the values read at ambient temperature.
