Notice
specimen must have the same temperature
Use
1. Open the cover
2. Pipette 2-3 drops of distilled water on the prism
3. Close the cover so that the liquid can be evenly
distributed over the entire surface of the prism to
prevent the formation of dry spots / bubbles
4. Wait 30 seconds for the temperatures to equalize
5. Aim the cap at the light source and look into the
eyepiece
6. You will see a circular field with several scales
7. Rotate the eyepiece to focus the scale
8. The upper part of the circular field should be blue

scale).
Custom measurement
1. Apply a few drops of the test sample to the prism
2. Close the cover
3. Aim it at the light source and look into the
eyepiece
4. The concentration value is determined on the
scale by the place where the blue and white
boundaries are shifted
Do not clean with corrosive or abrasive
substances
Do not rinse the device with water, just carefully
clean the prism (supplied cloth) to prevent water
from entering the prism
