New! NIST Certified Reference Standard

High quality calibration standard for portable surface roughness gauges. Ra values of 119.5 and 16.1; individually serialized and available certified to NIST.

The Phase II Reference Standard provides a reliable calibration tool which permits the technician to calibrate surface analyzing equipment to its peak efficiency. The SRG4600-500 shows the actual patch mean values of low and high microinch surfaces.

The surface of the Precision Reference Standard consists of a series of parallel, uniform, “V-shaped” grooves having an included angle of 150° between the sides. Since the surface character of the Precision Reference Standard is unlike normally machined surfaces, it is not recommended for use in visual and tactual comparison.
