DITRON 518 Bluetooth Digital Outside Micrometers | IP65 and 0-100mm Selection Malaysia
Choosing a Bluetooth Micrometer for Dimensional Inspection
The DITRON 518 Series Digital Outside Micrometers combine external dimension measurement with Bluetooth data output. They are intended for checking suitable shaft diameters, thicknesses and widths while supporting measurement transfer to a compatible receiving system.
The catalogue lists four models covering 0-100mm through separate 25mm measuring intervals. All models provide 0.001mm resolution, carbide measuring faces and a ratchet mechanism.
For manufacturing and quality control teams in Malaysia, selection should consider the component size, inspection tolerance and compatibility with the intended data recording system.
KEY FEATURES
Bluetooth Data Output
The catalogue specifies Bluetooth measurement output. This can support electronic recording when used with compatible receiving equipment and software.
Confirm the supported devices, operating systems, application, receiver requirements and data format before ordering. Bluetooth capability alone does not establish direct compatibility with Excel, an SPC system or every mobile device.
0.001mm Resolution
The display provides readings in 0.001mm increments, equivalent to 1 micrometre.
Carbide Measuring Faces
Carbide contact faces are specified for the measuring surfaces. Keep them clean and protected from impact to maintain consistent contact.
Ratchet Mechanism
The ratchet helps apply measuring force consistently. Use it according to the operating instructions rather than applying excessive force through the thimble.
Painted Steel Frame with Heat-Insulating Grip
The catalogue specifies a painted steel frame with a heat-insulating holder. Use the designated grip to limit direct hand contact with the frame.
Hold and ABS Functions
The catalogue lists data hold and absolute measurement functions. Follow the manual for reference setting and switching measurement modes.
IP65 Catalogue Identification
The product heading identifies the series as IP65. Confirm the operating and cleaning instructions for the intended workshop conditions.

HOW TO SELECT THE CORRECT RANGE
Match the Model to the Component
Choose the measuring interval that contains the required dimension.
For example, a 40mm shaft requires the 518-50. An 80mm component requires the 518-100.
The 518-100 does not measure continuously from zero to 100mm. Workshops checking parts across the complete span may require several sizes.
Check Contact Access
Confirm that the frame fits around the component and that both measuring faces can reach the intended surfaces.
Shoulders, flanges and recessed features may require a different micrometer contact arrangement.
Compare Accuracy with the Drawing Tolerance
Resolution and accuracy are separate specifications.
The 518-25 displays in 0.001mm increments but has a listed accuracy of ±0.003mm. It should not be described as having ±0.001mm accuracy.
Temperature, alignment, contact force and reference quality also affect the complete measurement.
WHAT BLUETOOTH ADDS TO THE INSPECTION WORKFLOW
Bluetooth output can reduce the need to manually retype readings when the receiving system is compatible and configured correctly.
Before introducing it into production inspection, check:
The supported receiving device and software.
Whether a separate receiver or adapter is required.
How the Data button sends a reading.
How units and decimal places appear in the receiving system.
How each reading is linked to the correct part and feature.
What happens if transmission is interrupted.
Test the complete recording workflow with known readings before relying on it for inspection records. Data transfer does not replace measurement verification.
TYPICAL APPLICATIONS
Machined Shaft Inspection
Check external diameters during production or final inspection. Measure additional positions where required to identify dimensional variation.
Component Thickness Checks
Measure suitable opposing surfaces within the selected range. Soft or compressible materials require consideration of measuring force.
Repeated Production Measurements
Use a consistent reference and contact procedure when checking batches of similar components.
Electronic Inspection Records
Transfer readings to a compatible recording system after confirming the connection method and software requirements.
These applications are relevant to manufacturing teams in Selangor, Penang, Johor and other industrial areas in Malaysia.
BASIC MEASUREMENT WORKFLOW
1. Clean the contacts and workpiece.
Remove chips, dirt and residue from both measuring faces and the component.
2. Verify the reference.
Follow the manufacturer’s setting procedure. Models above 25mm require a suitable reference for their measuring interval.
3. Confirm the units and mode.
Check whether the instrument is displaying millimetres or inches and whether the intended measurement reference is active.
4. Align the micrometer.
Position the required dimension along the spindle axis without tilted contact.
5. Apply consistent force.
Use the ratchet gently and consistently.
6. Read or transmit the measurement.
Allow the reading to stabilise, then record it or use the data transfer function as instructed.
7. Verify the record.
Check that the received value, unit and part identification are correct.
CARE AND ROUTINE CHECKING
Protect the measuring faces from impact and avoid measuring hot components when temperature differences could affect the result.
Clean and dry the instrument according to the manufacturer’s instructions after workshop exposure.
If readings become inconsistent, check cleanliness, reference setting, alignment and ratchet operation. If data transfer fails, check the receiving system separately from the measuring function.
