Surface-Finish Scales
Compare your surface finish to one of the swatches on these scales. The finishes are expressed in microinches (µ").
30-swatch scale comes with a chart to correlate the finishes with CLA and ISO N scales.
Economy Surface-Finish Scales
Compare your surface finish to one of the swatches on this scale. The finishes are expressed in microinches (µ").
| No. of Swatches | Scale | For Surface Type | Surface Finish Range, microinch | Lg. | Wd. | Material | Each | |
| 18 | AA, Ra | Flame Cut, Ground, Milled, Turned | 16-500 | 5" | 3 1/2" | Plastic | 000000 | 000000 |
Surface-Finish Scales with Certificate of Calibration
This scale comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy. Compare your surface finish to one of the swatches on the scale. The finishes are expressed in microinches (µ").
| No. of Swatches | Scale | For Surface Type | Surface Finish Range, microinch | Lg. | Wd. | Material | Each | |
| 22 | Ra | Ground, Lapped, Milled, Profiled, Turned | 2-500 | 2" | 5 3/8" | Nickel Alloy | 0000000 | 0000000 |
Surface-Roughness Testers
These units test for the most popular parameters, such as Ra, Rp, and Rq. You can also set an upper and lower limit for go/no-go readings, or test for a specific standard, such as ANSI, ISO, JIS, or VDA. Tester can save up to 10 readings and can take 1,000 readings on a single charge. It has an RS-232C port for a direct connection to your PC.
Use the SPC data output cable (sold separately) to connect your tester to a Mitutoyo miniprocessor.
