Calibration standards for polarimeters

Calibration standards for polarimeters

PQP- and PQE-quartz control plates

For a steadily high measurement accuracy

Like all measuring devices, polarimeters should be calibrated and adjusted on a regular basis. Sugar solutions are widely used as a standard for this purpose. Their disadvantage: They always have to be freshly produced for measurements. User errors during the initial weighing are difficult to prevent, and the high temperature dependency of the respective solutions also needs to be taken into account. Optically active quartz which is cut from mono-crystals is better suited for the calibration and adjustment of polarimeters. We offer you a selection of PTB-certified premium quartz control plates and (more cost-effective) quartz control plates with PTB traceable factory certification. We recommend re-qualification by our in-house service every 3-5 years.
