Krüss PQP-17 controle plaat Polari Quartz Professional +17°

Calibration standard for permanently highest measurement accuracy

Like all measurement devices, polarimeters should also be calibrated and adjusted regularly. Sugar solutions are widely used as a standard for this purpose. Their disadvantage: they always have to be measured freshly produced for measurements. User errors during weighing are virtually unavoidable, and the high temperature dependency of the respective solutions must also be taken into account. Optically active quartz crystals, which are cut and ground from mono-crystals, are better suited for the calibration and adjustment of high-precision polarimeters. We offer you a selection of PTB-certified Premium quartz control plates and (more cost-effective) quartz control plates with a factory certificate traceable to the PTB. We recommend requalification by our service department every 3-5 years.
