Saccharomat V sokeripolarimetri
With its worldwide unique quartz-wedge technology, the Saccharomat V is a fully automatically compensated sugar polarimeter. The working principle with quartz wedges is unique and unrivalled in accuracy until today. This Polarimeter does not need recalibration and will deliver reliable results throughout the entire product lifetime. Energy saving LED light sources keep maintenance efforts minimal.
As quartz has an optical rotatory dispersion (ORD) almost identical to that of a sucrose solution, SCHMIDT + HAENSCH developed a unique mechanism using a quartz wedge to compensate for small wavelength shifts. In other words, quartz and the sample react in an identical way to small shifts of wavelength, and these shifts are automatically compensated and the effect becomes irrelevant. This ensures long time stable high precision measuring results without the necessity of recalibration over the lifetime of the instrument. Beside the unnecessary recalibration the Saccharomat V uses an energy saving LED, keeping the maintenance efforts minimal. The functionality of the device can be monitored using triple quartz control plates.
