Trimos’s Universal Gage Calibration System model Labortory500

This micrometer is manufactured in a state-of-the-art ISO 9001 certified facility filled with modern machines such as Haas CNC milling centers, Brother CNC milling centers, Haas CNC turning centers just a few examples on the 50,000 sq. ft. CNC shop floors. Each micrometer is checked at 10 data points for maximum error tolerance with high precision gage blocks and also conducted inspection on parallelism and flatness by optical flat in a strict temperature controlled environment. The critical benchmark inspection media such as gage block are inspected periodically on world-known Swiss made calibration machines such as Switzerland’s Trimos’s Universal Gage Calibration System model Labortory500 and Germany’s Carl Zeiss Jena model 0-3000 mm calibration system for oversized length calibration.

  • accuracy of 0.00005"x(3+N+L/2)

  • If the length you will measure is 25.8", you can pick 2~2.5" micrometer head and 12", 8", 2" ,1" ,0.5" extension rods or 2~2.5" micrometer head and 12", 6", 4" ,1" ,0.5" extension rods.
  • Now the range of measurement is 25.5~26" (L=26), the number of the extension rods is 5 (N=5), then the accuracy is 0.00005"x(3+N+L/2)=0.00005"x(3+5+26/2)=0.00105"

Features

  • Each set consist of an inside micrometer head and a series of fully hardened and lapped extension tubular of different length
  • Positive locking nut on spindle
  • It's recommended that the inside micrometer with a rod be calibrated by a micrometer or ring gage
  • Quick, easy zero adjustment on the sleeve
  • Rod Diameter: 0.61"

c

  • Anvil and spindle are hardened and precision ground with microlap finish on end

c

  • Microfine graduation on satin chrome finish on spindle sleeve to increase readability

c

  • Coiled spring pressure contact type tubular are each marked with appropriate length

Very well built, compared this set against a set costing over $5,000 and they matched identically. We have purchased these multiple times and highly recommend. Great value for the price!

Bought these for our tool trailer. The price was right for what we need them for. We are industrial mechanics and do a lot of inspection work. To my surprise they were in perfect calibration against my starrett calipers. It wouldn’t matter the brand name of inside micrometers we use we would still check them with OD micrometers. Our main goal is to find stuff out of tolerances not machining parts. Although they would be capable of supporting the measurements. Great for tooling supplied to a group of mechanics.
