Certified SPG Standards

Used to verify the accuracy and operation of depth micrometer surface profile gages including the PosiTector® SPG and are an important component in fulfilling both ISO and in-house quality control requirements. SPG
  • Ideal for use in calibration labs
  • Standards consist of 4 sapphire test plates mounted in a precision ground steel base and supplied in a hard shell case
  • Sapphire test plates are individually serialized for traceability to PTB-includes a Certificate of Calibration
  • Certified and labeled in both Metric and Imperial units
  • Comes with a sample of Accuracy
  • Made in U.S.A

Standards Data

*Certified SPG Standards and included sample Certificate of Accuracy allow the user to certify the accuracy of depth micrometer surface profile gages in-house



SPG Separate - Same measuring specifications as the built-in SPG probe above but with a 3ft/1m cable for easier handling and greater accessibility onto a variety of surfaces.

SPG-C Separate - Similar in appearance to the SPG Seperate probe but with an extended measuring range and rounder tip. Ideal for measuring the profile of textured coatings and other surface profile applications. Range: 0 to 60 mils/1500 microns,
60° tip with a 500 micron radius.

SPG-T Separate - The new PosiTector SPG T Separate probe brings the ease and convenience of the PosiTector SPG family to concrete surface profile measurement. Measure up to 6 mm (250 mils) of profile without the hassle of replica putty or the vagueness of comparators.

Ideal for measuring the surface profile of concrete created by blasting, scarifying, grinding, acid etching and more.
