A portable refractometer (also referred to as hand held refractometer) measures the refractive index of aqueous solutions and is based on the relationship between refractive index and density. Density is used as a measure of dissolved material, which is important in the food and beverage industry, clinical laboratories for analyzing serum, and to researchers assessing sucrose density gradients. Refractometer ranges are in sucrose density or Brix units. A handheld refractometer is small and portable; the smallest has the dimensions of a pen. They have measurement ranges of up to 95% Brix, sample volumes of 3 ml or more, and operating temperatures between 5C and 100C. Ease-of-use attributes include continuous measurement capabilities, and fast and accurate readings that eliminate the need for user interpretation.

LED refractometers are particularly suitable for applications in low or artificially lit environments. The LED light incorporated in the prismatic cover of the LED Refractometer The PCE LED Refractometer is an analogue measuring device for determining the refraction property of different liquids. LED refractometers are particularly suitable for applications in low or artificially lit environments. The LED light incorporated in the prismatic cover of the LED Refractometer provides the necessary light for the measurement. Since the LED light is matched with the scaling of the LED refractometer, measurements are thus possible, for example, in basements without measurement errors caused by the artificial light.
- LED light in the prism cover
- Diopter adjustment for focusing
- Automatic temperature compensation
- Calibration via set screw
- Different models for many applications
- Prism cover interchangeable
