Micrometer Standards – PS4 with NPL certificate

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.
