Surface Profile Standards and Shim Sets are used for checking and adjusting calibration on PosiTector SPG, PosiTector RTR (and other depth micrometer probe) instruments.  Product details as follows:

• For the PosiTector SPG:
  • Certified Standards.  Typically used in calibration labs, these are available for any user who desires this level of verification.  Includes serialized and traceable height standards mounted to a metal plate.  Labeled in both metric and imperial units.
  • Certified Shim Set.  Premium option for everyday use with any depth micrometer using a fine-pointed probe (as well as the PosiTector SPG).  Includes 3 shims at 50/125/500 microns (2, 5, 20 mils).
  • Zero Glass Plate / Metal Shim (Non-Certified).  For training and quick checks for accuracy, each new SPG unit comes with this verification set, with replacement / additional units also available for purchase here.
• For the PosiTector RTR: (both models unless otherwise noted)
  • Certified Shim Set.  Premium option to check Peak Height measurements for accuracy verification on the RTR series (as well as other spring micrometer replica tape readers).
  • Non-Certified Shim Set (aka Precision Plastic Shim Set). Lower cost version of the above, ideal for everyday accuracy verification.
  • Single Check Shim.  This non-certified shim comes standard with each new RTR and is available as a replacement if desired, although it is more economical to purchase the above full set.
  • Check Tape.  This reusable tape is used to verify Peak Density, and is used on the RTR 3D model only.
