Product Description

Are you looking for simple bench top instrument to replace you old optical Abbe Refractometer or for a portable device, which offers more possibilities than normal portable Refractometers? In both cases the RA-130 Refractometer is most probably the ideal solution for you.

The RA-130 is both, a bench top and a portable Refractometer
You can either place the instrument on your bench and add a drop of sample onto the cell or immerse the cell directly into the sample.

The RA-130 Refractometer offers many features and possibilities
would only expect from a real bench top Refractometer like automatic temperature compensation with user defined temperature coefficients, user defined scales for concentration measurements, etc.

Full-fledged data handling
The RA-130 can not only store up to 1100 measurement results in its internal memory, it stores these values together with sample identifications and the date and time when the measurements have been performed. Thanks to a built-in IrDA interface, measured results can be transmitted to a printer or a personal computer at anytime.

The RA-130 is well prepared for all types of sugar concentration measurements
as it is equipped with the three most commonly used scales in the sugar industry: Brix, HFCS42 and HFCS55.

A graphical backlit display
and an intuitive menu structure provide an easy operation and a clear visualization of the measured values.

IDP-100 Printer

IDP-100 Printer

Dot matrix ink printer for GLP compliance.

  • Dot matrix printer with ink ribbon, prints on regular paper (width 57.5 ± 0.5mm).
  • 24 digits, 144 dots per line.
  • Automatic paper end detection – no loss of data!
  • 2 kB internal buffer memory. Advantage: Less time required per measurement, as the instrument does not have to wait until the results are printed out.
irDA - serial adapter

IrDA – Serial adapter

Adapter required to transmit data from an RA-130 Refractometer or a DA-130N Density Meter to a personal computer or a printer; ordering number 69-00733.

  • In order to connect this IrDA adapter to an IDP-100 printer, a 9 to 25 pin serial adapter (ordering number 64-01127-01) is required.
  • Some laptop computers are already equipped with an IrDA interface. In such cases no IrDA adapter is required.

Certified Standard Reference Material

Refractive index determination with laser interferometer

Liquid Refractive Index and Brix Standards

 

 

KEM does not only supply refractometers, it has was well a JCSS (Japan Calibration Service System) Accredited Calibration Laboratory (assessed on JIS Q 17025:2000 (ISO/IEC 17025:1999) where a wide range of certified refractive index standard reference material is produced. KEM has the JCSS accreditation number 0115. The refractive index of these standards is determined with a laser interferometer. All standards come with a certificate bearing the JCSS symbol which assures their traceability to National Measurement Standards of Japan which are recognized worldwide through the ILAC and APLAC MRA.

 

Certified Refractive Index Standard Reference Material

The refractive index standard reference material is always supplied as a set of two 10 mL vials: 1 vial of standard reference material water and one vial of standard reference material with a different refractive index (organic solvent). The refractive index standard reference material has a shelf life of 12 months.  The certified Brix standard reference material is supplied in sets of two 10 mL vials. This type of standard reference material has a shelf life of 1 month only.
