CURVED JAW SURFACES FOR INTERNAL MEASUREMENT
The manufacturer describes curved external measuring surfaces on the lower jaws as suitable for internal hole measurement.
Before selecting for a bore or internal opening, confirm:
• Minimum measurable internal diameter.
• Clearance for inserting and positioning the jaws.
• Required measuring depth.
• Correct internal reading method.
• Whether a jaw-width allowance must be added to the scale reading.
Do not assume the displayed scale reading directly equals the internal dimension without checking the operating instructions.
CHOOSING THE MEASURING RANGE
300mm, 500mm and 600mm Models
Available with 100mm or 150mm jaw dimensions for different access requirements.
800mm and 1000mm Models
Available with 150mm or 200mm jaw dimensions for larger components.
1500mm Models
Available with 150mm or 200mm jaw dimensions.
2000mm Model
The largest model listed, with a 200mm jaw dimension.
Maximum measuring range and jaw reach are separate selection criteria. Both must suit the workpiece.
LONGER JAWS AND ACCURACY
Longer jaws provide additional reach, but they do not provide higher stated accuracy.
For example:
Jaw dimension a: 150mm
Catalogue-stated accuracy: ±0.07mm
Jaw dimension a: 200mm
Catalogue-stated accuracy: ±0.09mm
Select the jaw length needed to reach the measuring surfaces while checking that the model’s accuracy meets the inspection requirement.
APPLICATIONS IN MALAYSIA
The DITRON 105 long jaw range can be considered for dimensional checks involving:
• Large machined rings.
• Accessible internal openings in housings.
• Fabricated components.
• Large mechanical parts.
• Maintenance and replacement-part assessment.
• Incoming inspection of larger components.
For engineering workshops and fabrication facilities in Selangor, Kuala Lumpur, Johor and Penang, a component drawing can help identify the required measuring range and jaw access.
For close-tolerance bore inspection, assess whether a bore gauge, inside micrometer or another measuring system is more appropriate.
VERNIER INCREMENT AND ACCURACY
The listed 0.02mm vernier increment describes the scale reading interval. It does not mean every model has ±0.02mm accuracy.
The model-dependent accuracy values on this page range from ±0.05mm to ±0.16mm, subject to confirmation of the catalogue’s interchanged column headings.
Large-component measurement also requires attention to instrument support, alignment, temperature and contact force.
BASIC MEASURING PROCEDURE
1. Clean the measuring surfaces and workpiece.
2. Check zero alignment and slider movement.
3. Confirm the correct reading method for the selected measuring faces.
4. Support the instrument and workpiece securely.
5. Position the jaws at the required measuring location.
6. Align the caliper with the dimension being measured.
7. Apply light, consistent contact force.
8. Read the main scale and vernier graduation.
9. Apply any manufacturer-specified allowance for internal measurement.
10. Repeat the measurement to assess consistency.
Avoid forcing the jaws or using them as levers.
CARE AND STORAGE
• Keep the scale and sliding surfaces clean.
• Remove chips before bringing the measuring faces together.
• Protect long jaws from impact and excessive force.
• 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 is the largest model listed?

What does 105-600/150 mean?
The catalogue lists this model with a 0–600mm measuring range and a 150mm jaw dimension a.
Can these calipers measure internal holes?
The catalogue specifically highlights curved external surfaces on the lower jaws for internal hole measurement. Confirm minimum opening and the correct reading allowance before use.
Are separate upper inside jaws included?
Separate upper inside jaws are not shown on this page. This design differs from the DITRON 106 series previously listed with upper inside jaws.
Do longer jaws improve accuracy?
No. Some longer-jaw versions have a larger stated permissible error than the shorter-jaw model at the same range.
Does the instrument require batteries?
No. It uses a mechanical main scale and vernier readout.
Can it measure depth?
A depth rod or depth measurement function is not specified on the supplied page.
Is the material grade specified?
The supplied page does not identify the material grade. Confirm this if required by your purchasing specification.
Why should the accuracy and resolution be confirmed?
The supplied table appears to interchange these column headings. Request a corrected specification before purchase.
Is a calibration certificate included?
The supplied page does not confirm that an individual calibration certificate is included. Specify documentation requirements when requesting a quotation.
