K1Digital Outside Micrometers
Outside micrometersare 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.
Starettmanufactures 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.
Features
- Starrett digital outside micrometers are used to measure the thicknesses of objects.
- They allow a minimum reading of ten-thousandths of an inch (0.0001 inches) from the vernier scale on their micrometer sleeve, with an accuracy of +/-00005 inches.
- Starrett outside micrometers have a digital counter for easy reading up to thousandths of an inch (0.001 inches).
- They have an extremely hard & stable one-piece spindle, micro-lapped carbide measuring faces, a frame with no-glare black finish and a thimble & sleeve with no-glare satin chrome finish for corrosion & wear resistance, accurate measurements and durability.
- Starrett outside micrometers are equipped with a ratchet stop for uniform adjustment and knurled ring-type lock nut for locking the micrometers at any reading.
Compatible Accessories
- Spanner Wrench: Raptor Supplies can deliver spanner wrenches for readjusting Starrett outside micrometers after cleaning or lubricating these micrometers.
- Standards: Micrometer standards / masters feature fixed dimensions and are used to perform basic calibration and accuracy checks on Starrett outside micrometers.
Standards and Approvals
- Starrett precision measuring tools like Starrett outside micrometers are traceable to the United States National Institute of Standards and Technology standards for meeting or exceeding their accuracy and performance requirements.
- Starrett outside micrometers are RoHS and REACH compliant for ensuring user safety and environmental health.
Installation
Starrett outside micrometers come factory assembled and can be operated just after taking them out of their packaging. However, it is recommended to calibrate Starrett outside micrometers before use to check the accuracy and get the best results.
Frequently Asked Questions
What are some points users need to remember while using Starrett outside micrometers?
- A drop of precision instrument oil / lubricant should be occasionally applied on the spindle & threads for proper wear resistance.
- Starrett outside micrometers should be periodically calibrated using a master / standard for maintaining accuracy.
- Starrett outside micrometers should be wiped clean & stored in a protective case after every use for preventing damage to its body. An air hose should not be used to clean the tool.
Does Starrett offer a warranty on Starrett outside micrometers?
Starrett offers a one year warranty (from date of purchase) on Starrett outside micrometers against defects in materials and workmanship, provided that the tool has not been abused or misused.
What are the three main types of micrometers?
- Outside micrometers: These outside micrometers measure the external dimensions of an object / tool.
- Inside micrometers: These inside micrometers are ideal for measuring dimensions like inside diameter of a hole, tube or pipe.
- Depth micrometers: These depth micrometers are suitable for measuring the depths of holes, recess, slots and steps.
