DITRON 103 vs 104 Alloy Vernier Calipers | Measurement and Scribing Applications Malaysia
Choosing a Vernier Caliper for Measurement or Marking Lines
The DITRON 103 and 104 Series Alloy Vernier Calipers serve different workshop purposes.
The 103 Series is designed for measuring external dimensions, internal dimensions, hole depth and steps. The 104 Series has scribing jaws for marking lines, with wear-resistant hard alloy embedded in the marking contacts.
Both series offer 150mm, 200mm and 300mm measuring ranges with a listed resolution of 0.02mm.
For machining, fabrication and maintenance workshops in Malaysia, the main decision is whether the instrument is required for dimensional inspection or for layout and scribing work.
103 SERIES: ALLOY VERNIER CALIPER
The DITRON 103 Series provides the measuring arrangements associated with a conventional vernier caliper.
Outside Measurement
The lower jaws contact suitable external features, such as component widths, thicknesses and outside diameters.
Inside Measurement
The upper jaws provide contacts for accessible openings and internal dimensions.
Depth Measurement
The depth rod measures suitable hole and recess depths when the reference end seats correctly.
Step Measurement
The step measuring surfaces support checks of accessible shoulders and step dimensions.

104 SERIES: ALLOY VERNIER CALIPER WITH SCRIBING JAWS
The DITRON 104 Series is specifically designed for marking lines.
Its marking jaws contain wear-resistant hard alloy, as stated in the catalogue. The drawing shows different lower jaw lengths, identified as a1 and a2.
This configuration should be selected according to the intended marking position and the reference surface available on the workpiece.
The supplied page does not identify the exact hard alloy grade. It should not be described as a specific carbide composition without further confirmation.

103 VS 104: WHICH SERIES SHOULD YOU CHOOSE?
Choose 103 for General Dimensional Checks
Select the 103 Series when the main requirement is external, internal, depth or step measurement.
Choose 104 for Scribing
Select the 104 Series when the main task is marking reference lines using dedicated scribing jaws.
Check the Jaw Geometry
The 103 and 104 models have different lower jaw configurations. Compare the drawing dimensions with the component and the intended operation.
Choose the Range Separately
A 300mm model provides more measuring capacity than a 150mm model, but requires more handling space. Choose a range that covers the task while remaining practical to position.
UNDERSTANDING 0.02MM RESOLUTION
Resolution describes the vernier reading increment. It does not establish the accuracy of every measurement or marked line.
For example, the 103-150 has a 0.02mm resolution and listed accuracy of ±0.03mm.
During scribing, the final line position also depends on the reference edge, contact consistency, instrument alignment and line width. Do not treat scale resolution as a guarantee of finished marking accuracy.
TYPICAL APPLICATIONS
Machined Component Inspection
Use the 103 Series for suitable dimensional checks during machining and maintenance.
Fabrication Layout
Use the 104 Series to mark reference lines before subsequent workshop operations.
Component Preparation
Scribing can help establish positions for further work where the material surface and drawing requirements permit marking.
Workshop Training
Mechanical vernier scales support training in scale reading, contact technique and reference selection.
These applications are relevant to engineering workshops in Selangor, Penang, Johor and other industrial areas in Malaysia.
BASIC MEASUREMENT AND SCRIBING PRACTICE
For Measurement
Clean the contacts and workpiece. Check the zero condition and verify against a suitable reference.
Align the correct measuring surfaces with the feature and apply gentle contact. Repeat the measurement to assess consistency before recording the result.
For Scribing
Confirm that marking the component surface is permitted. Prepare a clean reference edge and set the required dimension.
Secure the setting using the intended mechanism, then maintain consistent contact with the reference while marking. Avoid excessive force that could damage the contact or disturb the setting.
Check the marked position before continuing to the next operation.
CARE AND ROUTINE CHECKING
Protect measuring and scribing contacts from impact. Inspect for chipped points, burrs and rough sliding movement.
Keep the beam and scale clean. Do not use general measuring jaws as a substitute for dedicated scribing contacts.
The supplied page does not establish the complete body alloy composition, hardness, included accessories or calibration documentation. Confirm any required details when requesting a quotation.
FREQUENTLY ASKED QUESTIONS
What is the difference between the 103 and 104 Series?
The 103 Series is intended for dimensional measurement. The 104 Series has dedicated scribing jaws for marking lines.
What sizes are available?
Both series offer 0–150mm, 0–200mm and 0–300mm ranges.
What is the resolution?
The catalogue lists 0.02mm for all six models.
Can the 103 Series measure depth?
Yes. The catalogue identifies hole depth and step measurement among its applications.
What material is used in the 104 marking contacts?
The catalogue states wear-resistant hard alloy. The exact grade is not specified.
Do these calipers require batteries?
No. They use mechanical vernier scales.
Can scribed line accuracy be assumed from resolution?
No. Reference quality, alignment, contact technique and line width also affect the marked position.
What information helps with selection?
Provide the required range, drawing tolerance, component geometry and whether the main task is measurement or scribing.
