[Abstract]:

The composition of the refractometer:

1: light board

2: refractive prism

3: Zero correction screw

4: Eyepiece

5: rubber sleeve

Precautions in use:

1. In use, it must be carefully and carefully used strictly according to the instructions. Do not loosen the connection parts of the instrument arbitrarily. Do not drop, collide, or strictly avoid severe vibration.

2. After use, it is strictly forbidden to directly put it into the water for cleaning. Apply clean and soft flannel to wipe it clean. For the surface of optical parts, it should not be scratched or scratched.

3, the instrument should be stored in a dry, dust-free, oil-free and acid-free corrosion gas, so as to avoid optical parts corrosion or mildew.
