Brix Refractometer with Illumination

The Brix refractometer with automatic temperature compensation and LED light in the prism cover is an optical instrument that examines the behavior of light as it transitions from one medium to another. It is essential to keep both the prism and the prism cover clean, dry, and free of scratches.

This Brix refractometer operates on the principle of transmitted light and is suitable for examining transparent liquids. Unlike analog Brix refractometers, which typically rely on ambient light, this model features LED illumination in the prism cover. This allows for independence from ambient light and enables measurements even in low-light outdoor conditions.

The scaling is calibrated to the LED lighting, allowing measurements to be taken in cellars, laboratories, production halls, or workshops without the need to check and readjust the scale for the specific artificial light. The LED light is refracted at the interface between the sample liquid and the measuring prism and directed through a lens onto a disc with a measuring scale.

The refractive index of the liquid being examined determines the angle at which the light hits the lens from the measuring prism. The angle of light refraction determines which areas of the measuring scale are illuminated. The value for the tested liquid can be read on the scale at the boundary line between light and dark.

This illuminated Brix refractometer has a scale ranging from 0 to 32% Brix with a scale division of 0.2% Brix.
