Gar Precision Reference Standard with NIST Certification – PRS-100C

• The major advantage of the Precision Reference Standard is that it is the only calibrating block on the market to show its actual patch mean value of the low and high micro-inch surface as certified by the National Bureau of Standards.
• The value for the areas in the low and high micro-inch ranges show the readings from the five corresponding positions on each patch obtained as shown below.
