Polartronic NNIRW2 Automatic Sugar Polarimeter

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 handled simply via four function keys. It has a one line 16 character LCD display with the possibility to display laevorotating samples. The instrument is equipped with a simple software for test routines and instrument configurations and a configurable RS232 interface. Other interfaces (or additional) are available.
