Automatic Process Polarimeter: Propol Brochure

The Propol process polarimeter is ideal for online concentration measurements of optically active substances. Its high accuracy is achieved by an optical setup which makes use of the Faraday effect. The Propol process polarimeter combines reliability of results with process stability: no moving parts make the instrument free of wear. Its sturdy design is ideal for harsh process environments: the control unit can be placed away from the measuring unit in the control area.

Measuring ranges (°Optical Rotation)
Range ± 6° (see also the specifications for the interconnecting cable), resolution 0.001°. Optical rotation data is displayed with all concentration scales.

Individual scales
Three scales, CONC1, CONC2 and CONC3, each scalable by

• 4 standard solution of known concentration or by quartz standard
• 4 linear factor input
• 4 polynomial coefficients input for non-linear scaling

Preconfigured concentration scales

• 4 % Sucrose, range depending on optical cell length, e.g.0 - 65% for 10 mm.
• 4 % Glucose, range depending on optical cell length, e.g.0 - 65% for 10 mm.

Each concentration scale has menu-selectable resolutions of 0.1%,
0.01% or 0.001%.
