Hi, I noticed an error in the product listing. The description says "Contact Points Carbide-Tipped" However these caliper are just hardened steel, not carbide tipped (these are Mitutoyo 500-196-30, the carbide tipped equivalent model would be 500-159-30)

Thank you for noting this error in our web presentation. We will be updating it soon with the correct information.

Thank you for pointing out the mispelled word.

Thank you for pointing out that the presentation was missing the accuracy specification; it has now been added to the presentation. We are continually working to improve the content of our web pages in order to serve our customers and the value of user feedback in this effort is immense. The SBC-COMM can be used to interface the CPM1 with a computer; however the SBC-COMM was designed to be used with a Soleil-Babinet compensator. As a result, the included programs only include one micrometer specific LabVIEW VI with limited functionality (it only reads the output of the micrometer).

Does the computer interface SBC-COMM sold with the Soleil-Babinet compensator also work for th CPM1, same question applies to the digital micrometer head that appears to be made by the same manufacturer.

Please provide the resolution, precission, and accuracy of your measurement tools. Saying that the device accurately reads up to 0.001", implies that the accuracy specification (which is missing) would apply only to measurements of less than 0.001" which is not reasonable for these devices. For the calipers as well as the micrometer it seems that the number given for the strangely worded accurately reads specification is actually the display resolution which for a digital device is typically the resolution. What i really need to know is what the accuracy of the device.

It would be nice to have the digital micrometer head as a Rleated Product.

  • Converts from English to Metric with the Push of a Button
  • Thumbscrew Locks Micrometer Position
  • Compatible with SPC System

The CPM1 Digital Micrometer is an ideal inspection device used to precisely measure the thickness of almost all materials. The design features a non-rotating carbide-tipped spindle that eliminates torque on the work piece thus producing an accurate measurement while simultaneously minimizing the deformation and wear of the work piece. Although the SBC-COMM was designed for our SBC series of Soleil-Babinet Compensators, it can also be used to interface the CPM1 with a computer. The SBC-COMM package provides the equipment necessary to establish an interface between the CPM1 and a computer via an RS-232 interface along with a simple LabVIEW™ VI that reads the output position displayed on the micrometer.

The DGM05 Digital Indicator is an inspection tool commonly used to check the current position of a stage or the flatness of a breadboard or optical table.  It has a 1/2" (12.7 mm) measurement range with an easy-to-read LCD screen. In addition to this LCD screen, the front face includes buttons that switch between imperial and metric scales, reset the origin, switch the count direction with respect to the spindle, or power the unit on or off. Connection to a computer is possible via the top-located SPC output, however, the required SPC cable is not included.

Each unit has a Ø3/8" mounting barrel and includes an RBA1 Ø3/8" to Ø1/2" Barrel Adapter for increased mounting options. Two mounting options are shown in the images to the right and can be purchased by clicking on the View Imperial Product List or View Metric Product List links located below the images.
