Fully automatic refractometerIt is an instrument that uses light to test the concentration of liquids, used to determine refractive index, birefringence, and optical properties. Refractive index is one of the important physical constants of matter.

Fully automatic refractometerHow should maintenance be carried out?

1. The workbench should be sturdy and stable, without obvious impact and vibration, and without strong electromagnetic interference.

2. Sodium lamps have a certain service life, and continuous use generally does not exceed 4 hours. They should not be repeatedly turned on and off in an instant.

3. After the sodium lamp is turned on for at least 20 minutes, it can only emit light stably. When measuring or reading, it should be done when the sodium lamp is stable

4. Sodium lamps should be powered by DC circuits as much as possible.

5. The glass cover slips at both ends of the sample tube should be wiped dry with a soft cloth or lens wiping paper, and the nuts at both ends of the sample tube should be rotated to an appropriate position,

6. Tightness can easily cause stress damage to the cover glass, while looseness can lead to leakage.

After the measurement is completed, the sample tube must be cleaned and dried, and the lens should be kept dry and clean to prevent contamination from dust and oil stains.

8. The sample room should be kept dry and clean, and silicone gel should be placed to absorb moisture when the instrument is not in use.

9. The instrument should be placed in a dry and ventilated place to prevent moisture erosion. It should be used in an environment of 20C as much as possible. When moving the instrument

10. Handle with care and avoid vibration.

11. Light source If there is dust accumulation or loss in the sodium lamp, the casing can be opened for cleaning or replacement.

12. As the friction resistance in the mechanical department increases, the rear door panel can be opened and a small amount of bell oil can be added to the helical gear and turbine worm.
