Digital Refractometer
 
Short measuring times at maximum accuracy
High-precision Digital Lab Refractometer DR6000 series is suitable for mixing-ratio, determination of purity, quality and quantity control.

 
Fearures:
 
With a simple, intuitive touchscreen, all results and user management can be operated on the device.
The unit incorporates an integrated SQL database, for storing data, and allows for access via a network or standalone PC.
The DR6000 has an integrated Peltier thermostat for efficient temperature control, allowing very short measuring times at maximum accuracy.

Easy cleaning of the probe.

Interface and software package for full GLP compliance.
 
How does a Digital Refractometer work?
 
One major advantage of a modern digital refractometer is that sample preparation is no longer necessary.
Liquid samples can simply be placed on the measuring prism and the analysis begun.
Good practice requires that the calibration of the instrument is regularly checked, and this can be done by simply measuring the refractive index of a sample of distilled water.
 
One factor that must be considered is temperature: the refractive index of a substance varies with temperature, and so this must be carefully controlled. A digital refractometer will either incorporate a Peltier temperature control element or, in the case of less advanced instruments, a water bath controlled by thermostat.
 

APPLICATIONS

- Pulp and paper industries
- Beverage industry
- Food industry
- Sugar and sweetener industries
- Textiles industry
- Pharmaceutical industry
- Chemical industry
