Digital refractometers with Peltier temperature control DR6300-T

Digital refractometers with Peltier temperature control DR6300-T

High-Precisions Digital Refractometers Series

Maximum efficiency with automation

As a standard, the refractometer models DR6300-T and DR6300-TF are equipped with a Peltier element that controls the temperature of the sample up to 80 °C. There are four different models available for different requirements on accuracy, resolution and measurement range whereby you can access the same operation and functionality.

• Measurement of turbid or highly viscous samples
• With highly accurate internal Peltier temperature control
• Preinstalled and freely definable scales with conversions based on tables or formulas
• Chemical-resistant materials such as measurement prism made of sapphire, measuring tray made of stainless steel
• Intuitive operation via touch-screen display
• Complete data recording and backup including audit trail
• Flexible data export
• Compliance with global standards and norms

How does it work?

The measurement of refractive index, also called the index of refraction, is a straightforward process when using modern instruments. Nevertheless the generation of accurate and reproducible results demands that appropriate techniques are used and laboratory technicians are adequately trained. 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.
