The Starrett 673 Bench Micrometer is a high-precision instrument, ideal for bench use either in a shop environment or inspection laboratory. It can be used as a comparator measuring to fifty-millionths of an inch (0.000050in) or two-thousandths of an mm (0.002mm) or for direct measuring to .0001in or 0.002mm. Work lengths up to 2in or 50mm can be measured.

Starrett 673XZ Direct-Reading Bench Micrometer

• The base is a heavy, rigid casting, incorporating at the left end a movable anvil that actuates a linear, friction-free motion transfer mechanism between the anvil and the indicator
• The large thimble diameter, approximately 3in (77mm), makes possible widely spaced graduations that are easy to read without a vernier scale reference
• Advanced, staggered design and quick reading graduations in combination with Starrett no-glare satin chrome finish on both thimble and sleeve also contribute to easier, faster readings
• The head is furnished with a speeder and has a special ring-type lock nut that firmly holds the spindle at any setting without distortion
• Another useful feature is the adjustable work table centered beneath the anvil and spindle. Work can be accurately aligned between the anvil and spindle by adjusting the table to the proper height and locking it in position
• The spindle and anvil are carbides faced for long life
• To read to ten-millionths of an inch (.000010in) or 0.0001mm, this bench micrometer can be used with both the 776 Electronic Digital Gage Amplifier (LVDT probe 776-2Z) or on the 717 Analog Amplifier (LVDT probe 715-2Z); Both require 673A adapter
