Figure G1.1  DIGM1Q digital micrometers can transmit measurements to a computer either with a CAB-SPC2 SPC data output cable (shown here) or a DIGMBT1 Bluetooth wireless transmitter.

• Measure Dimensions Up to 4.00" with a 1.00" Range
• Spindle Thread Pitch Provides 2.0 mm Spindle Movement per Thimble Rotation
• Ratchet Thimble Mechanism
• Converts from Imperial to Metric with the Push of a Button
• Lever to Lock the Spindle Position

These digital micrometers are designed for taking outside measurements up to 4" (100 mm) and have a 1" (25 mm) total measurement range. They feature a ratchet thimble mechanism that allows for single-handed use and provides a consistent measuring force. An easy-to-read digital display provides a high resolution readout to 0.00005" (1 µm). The 2 mm fast spindle thread pitch enables the spindle to travel four times farther per full rotation of the thimble compared to micrometers with a standard 0.5 mm thread pitch. The anvil and rotating spindle are both carbide-tipped to resist wear on the flat surfaces. Except for the DIGM1Q, each micrometer includes a standard bar to set the zero at the minimum position. All micrometers come with a fitted plastic case for protection and storage.

The DIGMBT1 is a Bluetooth wireless transmitter that can be attached to any DIGMxQ digital micrometer. A computer or phone with Bluetooth capability can connect simultaneously to up to seven different measurement tools, each equipped with its own DIGMBT1 transmitter. With this setup, measurement data can be sent directly to programs like Microsoft Excel for improved efficiency when performing repeated measurements. For software related to wireless data input and instructions on how to connect the DIGMBT1 to a micrometer, please see the Software tab.

For a plug-and-play alternative, the CAB-SPC2 USB cable allows direct data transfer from DIGMxQ micrometers to a computer—no additional software required.

• Measures Dimensions up to 1.00" (25.4 mm)
• Non-Rotating Spindle
• Linearly Encoded Digital Readout
• Converts from Imperial to Metric with the Push of a Button
• Compatible with SPC System
• Lever to Lock the Spindle Position

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.

Please note that the CPM1 Digital Micrometer is not compatible with the DIGMBT1 Bluetooth wireless transmitter or CAB-SPC2 cable for SPC data output. For computer connectivity with the CPM1, we offer the SBC-COMM package which 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.

Figure G3.1  ANM1 Micrometers used to Measure the Diameter of an F25USN1P Threaded Bushing

• Measures Dimensions Up to 4.00" (100 mm)
• 1.00" (25 mm) Measurement Range
• Lever to Lock the Spindle Position
• Ratchet Stop Mechanism

These analog micrometers are designed for taking outside measurements up to 4" (100 mm) and feature a 1" (25 mm) measurement range. The design includes a ratchet stop mechanism and laser-etched scales on both the thimble and sleeve for easy measurement. Both the anvil and rotating spindle are carbide-tipped to resist wear on the measuring surfaces.

Our selection of imperial analog micrometers (Item #s ANM1, ANM2, ANM3, and ANM4) feature a thimble scale with 0.001" graduations as well as a high-resolution vernier scale with 0.0001" graduations (See Figure G3.3). Metric models (Item #s ANM25/M, ANM50/M, ANM75/M, and ANM100/M) feature 0.01 mm graduations on the thimble scale and do not include a vernier scale. Except for models ANM1 and ANM25/M, each micrometer includes a standard bar to set the zero at the minimum position. All micrometers come with a fitted plastic case for protection and storage.
