DITRON 623 Series Centre Distance Digital Calipers with Conical Tips | 150mm to 600mm Malaysia
DITRON 623 Series Centre Distance Digital Calipers
The DITRON 623 series features conical measuring tips for checking centre distances and edge-distance dimensions associated with circular holes.
Five models are listed, with measuring ranges from 5–150mm to 5–600mm. All models have a 0.01mm display resolution, while catalogue-stated accuracy varies by range.
For machining workshops, fabrication facilities and inspection departments in Malaysia, selection should consider hole geometry, centre spacing, contact access and required tolerance.

CENTRE-DISTANCE MEASUREMENT
The conical contacts are intended to locate against suitable circular-hole features so the instrument can measure the spacing between their centres.
Correct seating is essential. Burrs, damaged hole edges, chamfers and unequal contact depths can affect how the tips locate.
Confirm the permitted hole diameter range and seating method before selecting. The catalogue’s 5mm diameter entry does not by itself establish the complete range of hole sizes that can be measured.
EDGE-DISTANCE MEASUREMENT
The catalogue also lists edge-distance applications.
Before purchase, define the exact dimension on the component drawing. Distance from a hole centre to a reference edge is different from the clearance between the hole edge and that reference.
Confirm the required contact arrangement, reference-setting procedure and any allowance needed for the intended measurement.
MEASURING CONFIGURATIONS
The catalogue illustrates several contact arrangements.
Confirm:
• Which arrangement is supplied with the selected model.
• Whether contacts are adjustable or replaceable.
• Whether additional tips are included or ordered separately.
• The reference procedure after changing the setup.
• Accuracy applicable to the intended configuration.
Do not assume all illustrated configurations or accessories are included.
CHOOSING THE MEASURING RANGE
For supported measurements between 5mm and 150mm, with ±0.05mm stated accuracy.
Provides additional capacity up to 200mm, with ±0.07mm stated accuracy.
Provides capacity up to 300mm, with ±0.09mm stated accuracy.
Provides capacity up to 500mm and larger drawing dimensions a and b, with ±0.09mm stated accuracy.
The largest listed model provides capacity up to 600mm, with ±0.10mm stated accuracy.
Choose according to both the spacing and the tolerance required. A larger range does not automatically provide higher accuracy.
APPLICATIONS IN MALAYSIA
The DITRON 623 series can be considered for:
• Hole-spacing checks on machined plates.
• Fabricated bracket inspection.
• Fixture and jig dimensional checks.
• Accessible flange hole-spacing measurements.
• Maintenance and replacement-part comparison.
• Incoming inspection of drilled components.
For workshops and factories in Selangor, Kuala Lumpur, Johor and Penang, provide a drawing showing the required dimension and hole details when selecting a model.
A single centre-distance reading does not establish the complete position of a hole pattern or full compliance with geometric tolerances.
RESOLUTION AND ACCURACY
All listed models have a 0.01mm resolution. This describes the displayed increment.
Catalogue-stated accuracy ranges from ±0.05mm to ±0.10mm. The 0.01mm display does not establish ±0.01mm accuracy.
Measurement results also depend on:
• Tip seating.
• Hole edge condition.
• Contact alignment.
• Reference setting.
• Measuring force.
• Temperature and instrument condition.
ZERO-SETTING AND UNIT CONVERSION
Zero-setting at any position allows a reference to be established for comparative measurements.
Follow the operating instructions when setting the reference, particularly after adjusting the contacts.
Millimetre/inch conversion is also listed. Changing units does not change measurement accuracy.
The catalogue’s wording about relative and absolute measurement conversion does not explicitly establish a coded absolute encoder or reference retention after power loss.
BASIC MEASURING PROCEDURE
1. Identify the required centre or edge-distance dimension.
2. Check that the contact arrangement suits the holes and reference surfaces.
3. Clean the tips and workpiece.
4. Check for burrs or damaged contact locations.
5. Establish the reference according to the operating instructions.
6. Seat the conical tips correctly.
7. Keep the instrument aligned with the required measuring direction.
8. Apply light, consistent contact force.
9. Read and record the result.
10. Repeat the measurement to assess consistency.
Avoid forcing the tips into holes or using them to remove burrs.
CARE AND STORAGE
• Protect the conical tips from impact and wear.
• Keep the beam and sliding surfaces clean.
• Avoid excessive contact force.
• Do not measure hot or moving components.
• Follow the supplied battery and cleaning instructions.
• Verify the reference after contact adjustment.
• Store with the measuring tips protected.
• Check performance against suitable reference standards according to your quality procedure.
The supplied page does not explicitly specify battery type, rechargeable operation, Bluetooth capability, IP rating or material grade.
FREQUENTLY ASKED QUESTIONS

Are all illustrated tips included?
The page does not confirm the supplied accessory package. Specify the required configuration.
Can it check a complete bolt-circle pattern?
It may provide supported distances between accessible holes, but a complete pattern assessment requires an appropriate inspection method.
Can it switch between millimetres and inches?
Yes. Unit conversion is listed.
Is a calibration certificate included?
The supplied page does not confirm inclusion of an individual calibration certificate. Specify documentation requirements when requesting a quotation.
