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.

| Description | Refracto is a hand-held and a benchtop refractometer in one.You either place the instrument on a flat surface and add a drop of sample onto the measurement cell or immerse the cell directly into the sample.
Features
Glass prism
Refracto determines refractive index using the total reflection method. Refracto is a hand-held and a benchtop refractometer in one.You either place the instrument on a flat surface and add a drop of sample onto the measurement cell or immerse the cell directly into the sample.
Features
Glass prism
Refracto determines refractive index using the total reflection method. The glass prism of the measurement cell is held by a stainless steel ring.Refracto even measures dark samples correctly. You no longer need to rely on error-prone readings of dark/bright transitions as with optical instruments.
Temperature compensation
The refractive index of a sample depends on temperature. During measurement, Refracto determines the temperature and then corrects the refractive index to a standard temperature of 20 °C or any other temperature the user defines. To make quick measurements of different types of samples, you can easily switch between up to 10 user defined correction coefficients.
Plain language interface
The backlit LC-Display of Refracto shows your results and settings in plain language. The simple and intuitive menu structure allows you to change the settings within seconds. You hardly need an instruction manual.
Ease-of-use
The clearly labelled keyboard makes operation easy and efficient. As soon as you press the measurement key, the result is displayed in the desired units on the backlit LC-Display.
Comprehensive result storage
Refracto stores up to 1100 results including sample identification, measurement unit, temperature compensation coefficient, date and time.
Transfer your data whenever you want
You are free to transfer the data (together with an instrument identification) to a PC or printer any time using the IR interface. For this purpose an infrared / RS232 converter (51325006) is required. Appropriate PC software comes with the instrument....

Features
Sapphire prism
Refracto determines refractive index using the total reflection method. The prism of the Refracto 30GS is made of sapphire and held by a ring of hard gold plated brass. Sapphire has a higher refractive index and a better thermal conductivity than glass. For this reason the Refracto 30GS has an extended measuring range and registers the sample temperature more quickly.
Refracto even measures dark samples correctly. You no longer need to rely on error-prone readings of dark/bright transitions as with optical instruments.
