Usage Method: Open the lid (3), use a soft cloth to carefully clean the detection prism (2). Place a few drops of the test solution on the detection prism, gently close the lid to avoid air bubbles, and spread the solution evenly across the prism surface. Aim the instrument's light-entry plate (3) at the light source or a bright area, look through the eyepiece to observe the viewfield, and turn the eyepiece adjustment knob (6) to make the blue-white boundary in the viewfield clear. The scale value of the boundary indicates the concentration of the solution.
Notes: This instrument is a precision optical instrument. Please note the following points when using and maintaining it:
1. Use with caution and strict adherence to the instructions. Do not loosen any connection parts of the instrument, do not drop or collide with it, and strictly prohibit any severe vibration.
2. After use, do not directly put it into water for cleaning. Use a clean soft cloth to wipe it. For optical surfaces, do not cause scratches or damage.
3. The instrument should be stored in a dry and non-corrosive gas environment.
4. Avoid the loss of spare parts.
The adjustment range of the 6th dioptre adjustment knob and the 7th ocular lens is within 2 cm vertically, so the component's disengagement is caused by operating beyond the 2 cm range, which does not fall under quality issues but is an operational error. The store will not be held responsible for this. You can contact us by phone for instructions on installation.
