The S+H POLARTRONIC Automatic Polarimeters are truly in a class by themselves. Their measurement speed and accuracy are unmatched in the industry.

Polarimeters, by definition, determine the optical activity of a solution by means of a rotating analyzer and an optical encoder. S+H POLARTRONIC Automatic Polarimeters make use of a (S+H patented) direct, electronic interface between the analyzer and the optical encoder. This technique allows for exceptional speed in measurements and consistent accuracy across the entire measuring range. All other manufacturers employ mechanical linking of the analyzer and optical encoder. This results in much slower measuring time, inconsistent accuracy across the measurement range, and shortened service life due to mechanical wear and tear.

S+H N-Series Automatic Polarimeters feature accuracy of ±0.01°. Instruments are available in single and multiple wavelength configurations. All models come standard with halogen light sources, backlit LCD displays, password protection, printer and data ports, & optional USB ports.

A wide selection of S+H samples cells and quartz control plates are also available.
