Optical refractometer care and maintenance

Optical refractometer care and maintenance
1. The zero adjustment and measurement of refractometer should be carried out at the same temperature. If the temperature changes greatly, the zero should be adjusted once every 30 minutes.
2, the prism must be thoroughly clean, because any residual impurities may cause measurement errors.
3. After use, do not wash the instrument with water to avoid water entering the instrument.
4, because it is a precision optical instrument, should be handled lightly and very careful, do not touch and scratch the surface. Should be kept in a dry, clean, corrosion-free environment to prevent mildew and blurring. Avoid collisions in transit.
5, if the user follows the above method to use the instrument, it can not be damaged, the optical performance will not change.
6. Special care should be taken when testing the electrolyte. Because it contains sulfuric acid, plastic suckers must be used to keep it away from eyes and skin. refractometer
