Precision Reference Standard and Stylus Check shows actual patch mean values certified by the National institute of Standards and Technology (NIST). Calibrate your surface analyzing equipment to peak efficiency. The 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 on the market to show the actual patch mean values of Low and High Microinch surfaces and certified by N.I.S.T. 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 or tactual comparison. Report of Calibration by N.I.S.T. The Property of surface Roughness in the 125 Microinch Range and below is maintained by N.I.S.T. by means of master Roughness specimens conforming to ANSI-B 46.1. The master specimens were calibrated by Measuring their surface Profile With a Stylus instrument which in turn was calibrated by an interferometrically Measured step. The areas under the Profile curves were then Measured and the Roughness average computed. The Accuracy of this Measurement is 2% for the 119.5 and 1 Microinch for the 16.1. Dimensions: 2 1/2" x 3 3/4" Has actual mean patch values. Each duplicate of master plate Tested and certified by N.I.S.T. Conforms to ANSI-B 46.1-1985. Set No. 16037, Made of pure Electroformed Nickel. Provided With Protective Case.

Fowler 52-664-609-0, 10X Pocket Optical Comparator Set with 9 Reticles and Illuminator Attachment
Fowler's 10X Pocket Optical Comparator magnifies images which are sharp, undistorted and free of aberrations. Convenient for checking angles, thread measurements, hole sizes and more. This 10X comparator is widely used by machinists, toolmakers and inspectors in the industry. Features Scales are photo-etched into a glass reticle which is placed in actual contact with the measured object, obtaining simultaneous enlarged images of the scale. Reticles (protected in individual plastic cases) are easily interchanged by a screw-in mount. Measures radii, diameters, angles, hole sizes, pitch and thicknesses. With the illuminator attachment, the comparator converts into a self-contained illuminated measuring magnifier.
Radius Gage Sets are Made of rust-Proof steel, satin chrome Finish. Each Gage is marked With its radius Size. Each Gage has 5 Measuring surfaces for convex and cocave radii. All Sets furnished in vinyl Case. Model No. 16029, 8 Piece Set Without Holder, 11/16" to 1 1/2" in fractions of 16ths.
