Premium quartz control plates from the company A.KRÜSS Optronic GmbH

We offer our customers three different quality categories and optical angles of rotation. Our quartz control plate PQE "Economy" offers a measurement accuracy of +/- 0.005° and is thus the ideal calibration standard for our P3000 polarimeter series. Our highly precise PQP "Professional" quartzes meet the highest requirements with regard to accuracy. With +/- 0.001°, the accuracy range of our P8000 polarimeter series is thus covered. Premium quartz control plates of the type PQP are available with five different rotation values as well as in left-rotating and right-rotating form. On request, your quartz control plate will be supplied with the respective test certificate of the PTB (Federal Physical Technical Institution) instead of a works certificate.

The quartz control plates are made of high-quality stainless steel and are thus corrosion-proof and scratch-resistant. They are pleasant to touch with a slim shape and are easy to hold; their heavy weight ensures secure positioning on the specimen holder.

Combined with the menu-driven calibration procedure of the P8000/P3000 polarimeter series, the quartz control plates allow very quick and easy calibration. The engraved serial number guarantees traceability which is necessary for any quality assurance. Furthermore the design allows compatibility with polarimeters from other manufacturers.
