About Digital Abbe Refractometer

Digital Abbe Refractometer 

Caltech India offers Digital Abbe Refractometer. A refractometer measures the extent to which light is bent (i.e. refracted) when it moves from air into a sample and is typically used to determine the index of refraction (aka refractive index or n) of a liquid sample.

The refractive index is a unit-less number, between 1.3000 and 1.7000 for most compounds, and is normally determined to five digit precision.

The refractive index is commonly determined as part of the characterization of liquid samples, in much the same way that melting points are routinely obtained to characterize solid compounds. It is also commonly used to:

• Help identify or confirm the identity of a sample by comparing its refractive index to known values.
• Assess the purity of a sample by comparing its refractive index to the value for the pure substance.
• Determine the concentration of a solute in a solution by comparing the solutions refractive index to a standard curve.

Unmatched Measurement Precision

Experience highly accurate readings with a precision of 0.0002 nD and a resolution of 0.0001 nD, making this refractometer ideal for sensitive laboratory and industrial measurements. The hard glass prism ensures durability, and sophisticated temperature control (automatic/manual) delivers consistent results across diverse sample conditions.


User-Friendly Operation and Data Management

The device boasts a digital LCD display for clear results, internal memory for easy data storage, and optional USB connectivity for PC export. With multilingual interface support and single-sample capacity, operations remain intuitive for various users. The calibration can be conducted both automatically and manually, streamlining maintenance and accuracy.
