Portable Refractometer Polarimeter
- Atago - REPO-1
- Can measure both brix and optical rotation of the sample
A fusion of index of refraction and angle of optical rotation - Making the invisible, visible-Brix can only indicate the overall amount of dissolved solids in a solution. With REPO-1, it is possible to determine if a product has been adulterated by measuring the optical rotation.
Announcing an All-in-One, refractometer and polarimeter hybrid unit. As little as 3mL sample, Repo-1 can measure both brix and optical rotation of the sample. With the press of a button, purity, international sugar scale, specific rotation, and concentration can be displayed. Users can also set an upper and lower measurement limit. An indicator light alerts the user if a measurement value is within the limits, allowing for optimal efficiency.RePo-1 can be utilized for many uses, including helping to determine the rate of crystallization in honey.
2 in 1
Brix alone can only indicate the overall amount of dissolved solids in a solution. With REPO-1, it is possible to determine if a product has been adulterated by measuring the optical rotation. For example, fructose rotates light to the left while glucose rotates light to the right. If a sample has been adulterated with glucose, it will make the optical rotation readings appear more positive than a pure solution.
Compact Size
Great portability, 10.1×16.0×3.8cm and weighs only 325g.
Automatically calculated scales
Press "User" to select the desired scale: Purity, International Sugar Scale, Specific Rotation, and Concentration.
Measurement evaluation indicator
Measurements are evaluated against pre-set tolerancelimits, and the result is indicated by green or red light. (Upper and lower tolerance limits must be set in advance to using this function)
