Stage micrometers, SM-4

The SM-4 is a linear X axis scale of one inch, and our most widely used stage micrometre. The SM-4 combined with traceable NIST calibration enables you to be efficient and reliable in your measurements. The superior quality of the line edge at divisions of 10μm makes it the preferred choice for high power magnification.1.0"/25 mm X-Axis Linear Stage MicrometerAvailable: Chrome on glass (G) as standard, chrome on opal glass (O) or chrome on quartz (Q) by request only as a custom.P: positive image (mostly clear or white); N: negative image (mostly opaque or black).
