STARRETT Digital Outside Micrometers

Digital Outside Micrometers

Outside micrometers are used to measure thickness or outer diameter of an object. These outside micrometers feature mechanical, digital or electronic displays. They have carbide, high carbon steel or stainless steel construction for strength, durability and abrasion resistance.
Starett manufactures measuring instruments, precision tools and gauges. Starrett digital outside micrometers are designed for accurately measuring external dimensions of components in laboratories, as well as metalworking, automotive & manufacturing facilities. They feature a balanced & tapered frame for providing accurate measurements in narrow slots & tight spaces, a knurled ring-type lock nut for sure & quick locking and a ratchet stop for uniform adjustments during opening / closing of the micrometers. These Starrett outside micrometers have a built-in, rotating analogue digit counter for measuring thousandths of an inch (0.001 inches) and an extremely hard & stable, single-piece spindle with a vernier scale for measuring ten-thousandths of an inch (0.0001 inches). They are equipped with micro-lapped carbide measuring faces (both anvil & spindle) for precise measurements, even after long periods of use.
Choose from a wide range of these Starrett outside micrometers, available in 0 to 1 and 1 to 2 inch ranges. Raptor Supplies also offers Starrett outside micrometers in variants having no displays (requires manual reading).

Uses

Starrett outside micrometers are used to precisely measure dimensions like thickness & outer diameters of an object or tool. These Starrett outside micrometers are ideal for production, quality assurance (QA) and inspection applications in metalworking and industrial processes.

Working Mechanism

• After calibrating Starrett outside micrometer and checking the accuracy, place the object / tool to be measured between the C-shaped jaw of the micrometer.
• Start rotating the thimble to move the spindle face towards the object. Turning the thimble exposes the stationary scale on the sleeve. Rotate the thimble till the spindle face touches the object.
• The ten-thousandth number of the measurement can be determined easily by the user by matching the most closely aligned vernier scale line with a line on the thimble.
• For getting the final measurement, add the lower range of the micrometer (0 or 1) to the left of the decimal point and the micrometer reading to the right of the decimal.
• These Starrett outside micrometers have a digital counter that displays measurements up to thousands of an inch for cross verification.
