S8 with NPL Certificate

These calibrated standards provide traceability for the precise calibration and confirmation of accuracy of optical measuring instruments, which is necessary under ISO provisions.

The glass discs are mounted in stainless steel slides with engraved serial numbers. Each slide is supplied in a polished wooden storage case to distinguish it as a traceable standard of high value. We can arrange for the calibration of its scales and grids to be carried out by the most appropriate laboratory to suit the customers requirements – the choice of laboratory is normally dependent on the nature of the calibration and the accuracy required.

  1. Calibration by NPL: The National Physical Laboratory carries out measurements at selected points on the scale and grids and issues a certificate of calibration. Order Code: NP. The NPL is the English equivalent of NIST.
  2. Calibration by UKAS accredited laboratory: A UKAS accredited laboratory carries out measurements at selected points on the scales and grids and issues a calibration certificate. Order Code: NA
  3. Measurement by Pyser-SGI, Graticules Division: For applications which do not require the accuracy or traceability provided by calibrations carried out by NPL or a UKAS accredited laboratory, we can provide a Certificate of Comparison. The scale or grid is compared with NPL calibrated in-house standards and a statement is provided on the accuracy of the item with respect to these standards. Order Code: GR

A Certificate of Comparison from Pyser-SGI compares the scale to a NPL calibrated in-house standards. A statement is provided on the accuracy of the item with respect to these standards.
