Overview
Enviro Testers ophthalmology handheld refractometer is used to measure the refractive index ND and average dispersion NF-NC of transparent, semi-transparent liquid or solid. The instrument can also be equipped with a thermostat, which can measure the refractive index ND at a temperature of 0℃-70℃ and measure the percentage of sugar concentration in the sugar solution.
