DITRON 112 Series Vernier Caliper with Standard Jaws | Large Component Measurement Malaysia
Selecting a Vernier Caliper for Large Internal and External Dimensions
The DITRON 112 Series Vernier Caliper with Standard Jaws is designed for large outside and inside diameter measurements. Its extended lower measuring jaws and upper inside measuring jaws provide access options for larger components.
The supplied catalogue lists measuring ranges from 0–300mm to 0–1500mm, with a 0.02mm resolution across the series.
For machining, fabrication and maintenance workshops in Malaysia, selecting the correct model requires checking measuring range, jaw reach, component access and accuracy.
KEY FEATURES
Mechanical Vernier Scale
The vernier scale provides a mechanical measurement reading without a battery. Operators read the main scale together with the aligned vernier graduation.
Good lighting and correct viewing alignment help reduce reading errors.
Extended Lower Measuring Jaws
The longer lower jaws provide additional reach when contacting suitable external dimensions or recessed features.
Jaw reach and measuring range are separate specifications. A longer jaw does not automatically provide a larger measuring span.
Upper Inside Measuring Jaws
The upper jaws provide contacts for suitable internal measurements. Check that the opening and surrounding geometry allow the measuring surfaces to seat correctly.
0.02mm Resolution
All listed models have a resolution of 0.02mm. Accuracy varies by model and should be assessed separately.

HOW TO CHOOSE THE CORRECT CALIPER
Check the Required Measuring Range
Start with the largest dimension to be measured. Allow enough clearance to position and remove the caliper without forcing the jaws around the component.
Check Jaw Reach and Access
Compare the jaw dimensions with the workpiece drawing. Shoulders, flanges and recesses may prevent the measuring surfaces from reaching the intended feature.
The a dimension identifies the lower jaw reach shown in the drawing. Check the full jaw profile as well as its length.
Compare Accuracy with the Drawing Tolerance
The 112-300/60 has a listed accuracy of ±0.04mm, while the 112-1500/200 is listed at ±0.11mm.
Both have a 0.02mm resolution. The scale increment does not establish the accuracy of the complete measurement.
Assess Handling and Support
Large calipers need stable handling. Support the instrument and workpiece so the beam and jaws remain aligned without excessive contact force.
TYPICAL APPLICATIONS
Large Machined Components
Check accessible external dimensions on housings, plates and other machined parts within the selected measuring range.
Internal Opening Checks
Use the upper inside jaws for suitable bores and openings where the contact geometry permits proper alignment.
Fabrication Inspection
Check component dimensions during fabrication and assembly, taking account of surface condition and drawing tolerances.
Maintenance and Replacement Parts
Compare accessible internal and external dimensions when assessing worn parts or replacement components.
These applications are relevant to engineering workshops in Selangor, Penang, Johor and other industrial areas in Malaysia.
BASIC MEASUREMENT PROCEDURE
1. Clean the workpiece and measuring faces.
Remove loose debris and check for burrs that could prevent correct contact.
2. Check the caliper.
Inspect the jaws, scale and sliding movement. Check the zero condition and verify performance against a suitable reference.
3. Select the correct measuring surfaces.
Use the intended contacts for the internal or external dimension. Confirm any applicable offset or reading procedure in the manufacturer’s instructions.
4. Align with the feature.
Keep the instrument square to the measurement direction and avoid tilted or partial contact.
5. Apply gentle contact.
Excessive force can affect the result, particularly when using longer jaws.
6. Read and repeat.
Read the main scale and vernier carefully. Remove and reposition the instrument to check consistency.
CARE AND CHECKING
Keep the scale and sliding surfaces clean. Protect the measuring jaws from impact and store the instrument with suitable support.
If readings become inconsistent, check cleanliness, jaw seating, alignment and operator technique. Persistent disagreement with a suitable reference warrants further inspection or calibration.
Confirm any required calibration documentation when requesting a quotation.
FREQUENTLY ASKED QUESTIONS
What is the resolution of the DITRON 112 Series?
The supplied catalogue lists 0.02mm for all models.
Does it need a battery?
No. Measurement is read from a mechanical vernier scale.
Can it measure internal dimensions?
Yes. The catalogue identifies inside diameter measurement as an intended application and shows upper inside measuring jaws.
Does a 0.02mm resolution mean ±0.02mm accuracy?
No. Resolution and accuracy are different. The listed accuracy varies by model.
Is the 500mm model code confirmed?
The supplied table prints 112-300/100 alongside a 0–500mm range. This discrepancy requires confirmation before ordering.
What information helps with selection?
Provide the largest measuring dimension, required tolerance, jaw reach and a component drawing or photograph.
