Fully automatic precise and high-resolution sugar polarimeter
Fully electronic circle polarimeter with rotating analyser directly coupled to the optical encoder
Accuracy of the instrument is stable over the whole measuring range
Various sample tubes for different applications are on stock
Possibility to connect the measuring head of a refractometer of DUR series so that two instruments can be controlled over one electronic unit and the values are displayed in the same display. This connection can be performed on existing instruments as well.
With a special software and this combination a purity analyser is created without the need for a PC

NIRW2 polarimeter are working at 589 and 882 nm. The advantage of the NIR instruments being that samples, if thoroughly filtered, do not have to be clarified, because at NIR-wavelengths, highly absorbent samples may also be measured easily. In order to be able to control the stability of the measured values, the optical density will automatically be on display.

The NIRW2-polarimeter is constantly giving the value of the sample in the International Sugar Scale, ISS. The so called Normal Sugar Solution of 26.0 g of pure sucrose, diluted to 100.0 cm3 with distilled water at 20.0 °C has a reading of 100.00 °Z in this scale. If the customer uses 13.0 g instead, the reading has to be doubled, which can be made automatically by using the scale “°Z*2”. For a weight of 6.5 g scale “°Z*4” can be used. The measuring value can also be displayed in angular degree.

The instrument is equipped with 4 freely definable function keys and a numeric keypad. The 8 line LCD display with 30 characters per line is configurable. The customer can program up to 30 special scales (glucose, mono sodium glutamat or other). The instrument has a versatile software for test routines and configurations. It is equipped with a configurable RS232 interface. Other interfaces (or additional) are available.
