REFRACTOMETERS

 Wide Range, High Precision

FJD refractometers have a wide measurement range: urine specific gravity, sugar concentration, freezing points of coolant, and many more. With advanced algorithms and a built-in light source, the brix meter presents accurate readings within 2s, with only a few drops of sample solution needed.

*Refractometer: A refractometer is an instrument used to measure the refractive index. When light passes from one substance to another, i.e., from air to solution, it bends its path. The more refracted the light is, the more concentrated the solution is.

No need to worry about going wrong with honey readings.
