The GAR #PRS Precision Reference Standard provides an economical calibration tool which permits the technician to calibrate surface analyzing equipment to its peak efficiency.  It is the only calibration block available to show the actual patch mean values of low and high microinch surfaces and certified by NIST.

There is a required $8.00 handling fee on all GAR orders.

Please call us for discounted pricing on multiple product orders!

The surface of the Precision Roughness 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, therefore it is not recommended for use in visual or tactile comparison.

Also available as the #PRSC option, which is individually serialized, calibrated and supplied with long-form NIST certification.
