CDR Series Digital Refrectometer

CDR 6000 Digital Refrectometer by Citizen Scale

Data Function:

Digital Laboratory refracto meters from A Citizen Optronic are setting new benchmarks on many counts. An intuitive touchscreen presents a clear overview of all data and functions and the integrated SQL database stores all data and allows external access via a network or standalone PC.

Parameter:

The refractive index can be a parameter in quantitative or qualitative analysis and quality assurance. Degrees of polymerization can also often be monitored frequently quickly and cost-efficiently without turbidity or the colour of the sample affecting measurement precision.

Preparation of Sample:

There is no longer any elaborate preparation of samples necessary. The sample is simply placed on the measuring prism and the measurement process is started.

Resistancy:

The flat stainless steel plate is easy to clean and is highly resistant to aggressive substances.

Peltier Temperature:

As the refractive index depends on the temperature of the sample, the refractometer should be tempered.The DR6000 series is thus available with integrated electronic temperature control by means of a Peltier element. This type of temperature control is faster and more reliable than previous water bath thermostats which can be connected to the digital refractometer without Peltier temperature control. It is thus possible to carry on using an existing thermostat.

Sample Measurement:

For continuous measurements or series of measurements with many samples and high volumes of samples, devices with flow measurement cells are available. A sample can thus displace the previous one, nonetheless achieving an accurate measurement result without cleaning the measuring prism after every measurement.

RS 232 Interface:

If a printer is connected to the RS-232 interface, the measurement result can be printed out either directly after the measurement or later.

Data Storage:

All stored measurement data can also be filtered according to different criteria and exported to a USB stick in .XLS (Excel) or .CSV format.

Memory Storage:

The integrated SQL database stores up to 99 user-defined measurement methods and the last 999 measurement results with all relevant data, such as date, time and user. An optional user management system with three authorization levels safeguards the settings against any inadvertant changes.

GLP Compliance:

The DR6000 series thus complies with all GLP requirements and is ideally suited for use in FDAregulated areas. Refractometers can be connected to a PC via an Ethernet interface or integrated in an existing network. If there is access to the Internet, remote maintenance and fault diagnostics are also possible. Dr6000 refractometers are sturdy, low maintenance and also extremely quiet - a quality which is often underestimated when it comes to constant use in a laboratory.
