Flexbar 3-Patch Precision Reference Standard – 16030-1

This latest addition Precision Reference Standard consists of three specimens formed onto a single gauge. The specimens are identified by surface texture symbols representing nominal Ra(roughness average) in both microinches and micrometers.

The Precision Reference Standard 3-Patch was developed to meet industry’s requirements for a versatile standard which would allow the user to perform several important calibration checks on many stylus type surface roughness measurement instruments.

The Precision Reference Standard not only allows the user to check the stylus condition and high-end amplification of his instrument, but provides a specimen which now allows the user to check the low-end amplification of his instrument more accurately than with previously available standards.

Dimensions: 2-1/2″ x 4-3/4″

The 3 Specimen Patches provided include:
– 118 Microinch (3.0 micrometer) specimen – to check high-end amplification and low-frequency count.
– 14 Microinch (0.35 micrometer) specimen – to check low-end amplification and middle-frequency count.
– Stylus Check Specimen- to check relative stylus condition and high-frequency count.
