Certified
Thickness Standards
for Coating Thickness Gages
by DeFelsko
|
Certified thickness standards are ideal for checking calibration and
operation of coating thickness gages and are an important component in
fulfilling both ISO and in-house quality control requirements. All
standards described below are supplied with a certificate of calibration
showing traceability to NIST / NPL. |

Precision Plastic Shim
Standards
Each Set consists of five (5)
color-coded shims and is supplied in a sturdy envelope. (One set
included with each PosiTector coating thickness gage).
Application
For various Thickness Gages -
particularly constant pressure probe type gages.
