Digital refractometers with Peltier temperature control DR6000-T
DR6000-T: DIGITAL REFRACTOMETER With Peltier temperature control, measurement range nD 1.3200–1.5800, measurement accuracy nD ±0.0001
As a standard, the refractometer models DR6000-T and DR6000-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
Short measuring times at maximum accuracy
Kruess offers series DR6000 Digital Refractometers for the Laboratory, for applications such as mixing-ratio, quality and quantity control, plus determination of purity.
Features
- With a simple, intuitive touch screen 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.
- Complies with all GLP requirements.
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.
