The main features of the fully automatic refractometer RA-620/RA-600 for petroleum products are:
1. Refractometer with touch screen LCD display, displaying refractive index, soluble solids, and concentration.
2. Built in fully automatic temperature control, total reflection measurement, easy operation, and fast measurement speed.
3. Using LED light source does not require replacing the bulb, and the measuring prism is sapphire wear-resistant and corrosion-resistant.
4. Digital refractometer, compliant with GLP standards, automatically stores results, inspection and calibration records.
5. The refractive index and concentration comparison table or calculation formula can be inputted to automatically convert the concentration value of the sample.
7. Standard sample non-volatile cover plate can prevent the impact of volatile samples during testing.
8. It can be connected to an external digital densitometer and various automatic samplers to simultaneously measure density and refractive index.
9. Chinese interface, simple and intuitive operation, high-precision measurement results, and ultra-high cost-effectiveness.
