LOWER NIB-SHAPED JAWS
The catalogue describes the lower jaws as suitable for inside and outside measurement. Their contact profile can be useful where the measuring surfaces require this jaw geometry.
For internal measurements, confirm:
• The minimum measurable opening.
• Clearance for inserting and positioning the jaws.
• Which contact surfaces should be used.
• Whether a jaw-width allowance must be added to the scale reading.
The listed range beginning at zero does not establish a zero minimum internal measuring size.
UPPER OUTSIDE JAWS
The upper jaws provide an additional arrangement for external measurement.
These are outside measuring jaws. They should not be confused with the upper inside jaws found on conventional universal calipers or the separately listed DITRON 106 series.
Check the upper jaw profile and dimension b against the workpiece before selecting.
CHOOSING THE MEASURING RANGE
300mm Models
Available with 60mm or 90mm lower jaw dimensions.
500mm and 600mm Models
Available with 100mm or 150mm lower jaw dimensions.
800mm and 1000mm Models
Available with 150mm or 200mm lower jaw dimensions.
Maximum opening and jaw reach are separate requirements. Both must suit the intended measuring location.
LONGER JAWS AND ACCURACY
Longer jaws provide additional reach, but they do not automatically provide higher accuracy.
For example:
Lower jaw dimension a: 150mm
Catalogue-stated accuracy: ±0.06mm
Lower jaw dimension a: 200mm
Catalogue-stated accuracy: ±0.08mm
The two 1000mm models are both listed at ±0.09mm. Use the specification for the exact model rather than assuming a general accuracy rule.
APPLICATIONS IN MALAYSIA
The DITRON 109 series can be considered for:
• Large machined component inspection.
• Accessible ring and housing dimensions.
• Fabrication workshop measurements.
• Internal dimensions suited to nib-shaped contacts.
• External measurements using the lower or upper jaws.
• Maintenance and replacement-part comparison.
For workshops and inspection teams in Selangor, Kuala Lumpur, Johor and Penang, a component drawing helps identify the correct jaw arrangement.
For close-tolerance bore inspection, assess whether an inside micrometer, bore gauge or another measuring system is more appropriate.
RESOLUTION AND ACCURACY
All listed models have a 0.02mm vernier resolution.
Catalogue-stated accuracy ranges from ±0.04mm to ±0.09mm, depending on model.
Resolution describes the reading increment. It does not mean that every model has ±0.02mm accuracy.
Large-component measurement also requires careful instrument support, alignment, temperature control and consistent contact force.
BASIC MEASURING PROCEDURE
1. Identify the required dimension and measuring surfaces.
2. Select the appropriate upper or lower contacts.
3. Clean the contacts and workpiece.
4. Check zero and slider movement.
5. Confirm the reading method for internal measurement.
6. Support the instrument and component securely.
7. Align the contacts with the dimension being measured.
8. Apply light, consistent contact force.
9. Read the main scale and vernier graduation.
10. Apply any manufacturer-specified allowance.
11. Repeat the measurement to assess consistency.
Do not force the long jaws against the component or use them as levers.
CARE AND STORAGE
• Protect the jaws from bending and impact.
• Keep the beam and sliding surfaces clean.
• Remove chips before bringing the measuring contacts together.
• Avoid measuring hot or moving components.
• Clean and dry the instrument after use.
• Follow the manufacturer’s maintenance instructions.
• Store with adequate support for the beam and jaws.
• Check performance against suitable reference standards according to your quality procedure.
FREQUENTLY ASKED QUESTIONS
What makes the DITRON 109 different?
It combines lower nib-shaped jaws for suitable ID and OD measurements with additional upper outside measuring jaws.
Are the upper jaws for inside measurement?
No. The catalogue identifies them as upper jaws for outside measurement.
What measuring ranges are available?
The page lists 300mm, 500mm, 600mm, 800mm and 1000mm models.
What is the vernier resolution?
All listed models specify 0.02mm.
Do longer jaws provide better accuracy?
No. Check the exact model specification. Some longer-jaw versions have a larger stated permissible error.
Can the lower jaws measure internal dimensions directly?
The catalogue lists ID capability, but the correct reading method and any jaw allowance must be confirmed.
Can it measure depth?
A depth measurement function is not specified on this page.
Does it require batteries?
No. It uses a mechanical main scale and vernier readout.
What material grade is specified?
The supplied page does not explicitly identify a material grade. Confirm separately if required.
Is a calibration certificate included?
The supplied page does not confirm inclusion of an individual calibration certificate. Specify documentation requirements when requesting a quotation.
