DITRON 107C & 107D Hook Vernier Depth Calipers | Groove Depth & Width Measurement Malaysia
DITRON Single and Double Hook Vernier Depth Calipers
The DITRON 107C and 107D series feature hooked measuring ends for accessing suitable groove surfaces and recessed features.
The 107C uses a single hook, while the 107D uses a double hook. Both series offer 150mm, 200mm and 300mm measuring ranges, a 0.02mm vernier resolution and a listed 100mm base dimension.
For workshops and inspection departments in Malaysia, select the hook arrangement according to the required dimension, entry clearance and reference surface.

All dimensions follow the manufacturer’s respective drawings and are in millimetres.
CHOOSING BETWEEN SINGLE AND DOUBLE HOOK DESIGNS
Choose the 107C when the single hook can engage the intended measuring surface with sufficient clearance.
Choose the 107D when its double hook profile better matches the required contact arrangement.
For both designs, confirm:
• The opening through which the hook must pass.
• Groove width and depth.
• Distance from the reference surface to the groove.
• Internal shoulders or obstructions.
• Space for seating the reference base.
• Clearance for withdrawing the instrument.
The listed 2mm dimension c does not by itself establish a 2mm minimum measurable groove width.
GROOVE DEPTH, WIDTH AND POSITION
Groove depth, groove width and distance from a reference face are different dimensions.
Although the catalogue lists these applications, the measuring method must match the contact surfaces used. Follow the manufacturer’s instructions and confirm whether a hook allowance, reference correction or difference between readings is required.
Do not assume that every measurement can be read directly without an allowance.
MEASURING RANGE SELECTION
150mm Models
For supported measurements within a 150mm capacity.
200mm Models
For features requiring additional travel beyond 150mm.
300mm Models
For supported measurements requiring up to 300mm capacity.
A longer measuring range does not guarantee access to a deeper groove. Hook geometry and the reference arrangement must also suit the component.
APPLICATIONS IN MALAYSIA
The DITRON 107C and 107D series can be considered for:
• Accessible internal groove inspection.
• Groove-position checks in machined housings.
• Recessed shoulder measurements.
• Maintenance and replacement-part comparison.
• Incoming inspection of grooved components.
• Machining workshop dimensional checks.
For engineering workshops in Selangor, Kuala Lumpur, Johor and Penang, a cross-sectional drawing helps identify the suitable hook design and measuring procedure.
RESOLUTION AND ACCURACY
All six models list a 0.02mm vernier resolution.
Catalogue-stated accuracy:
• 150mm models: ±0.03mm.
• 200mm models: ±0.03mm.
• 300mm models: ±0.04mm.
Resolution describes the reading increment. It does not establish ±0.02mm accuracy.
Reference seating, alignment, contact force, cleanliness and instrument condition also affect results.
BASIC MEASURING PROCEDURE
1. Identify the required dimension and reference surface.
2. Check hook insertion and withdrawal clearance.
3. Clean the base, hook and workpiece.
4. Verify the reference according to the operating instructions.
5. Seat the base securely.
6. Position the hook against the intended surface.
7. Apply light, consistent contact force.
8. Read the main scale and aligned vernier graduation.
9. Apply any specified allowance or calculation.
10. Repeat the measurement to assess consistency.
Avoid forcing the hook into the feature or pulling against it with excessive force.
CARE AND STORAGE
• Protect the hook from bending and impact.
• Keep the reference base and measuring contacts clean.
• Remove chips before measurement.
• Do not use the hook to clear debris.
• Avoid measuring hot or moving components.
• Clean and dry the instrument after use.
• Follow the manufacturer’s maintenance instructions.
• Check performance against suitable reference standards according to your quality procedure.
FREQUENTLY ASKED QUESTIONS
What is the main difference between the 107C and 107D?
The 107C has a single hook. The 107D has a double hook.
What ranges are available?
Both series list 150mm, 200mm and 300mm models.
Do both series have the same resolution?
Yes. All listed models specify 0.02mm.
Is the double hook model more accurate?
No. Accuracy is the same at corresponding measuring ranges.
Can they measure groove width?
The catalogue lists width measurement. Confirm the contact arrangement and reading method for the specific groove.
Can they measure groove diameter?
Groove diameter capability is not explicitly specified on this page.
Do they require batteries?
No. Both use mechanical main scales and vernier readouts.
Is the material grade specified?
The supplied page does not explicitly identify a material grade.
Is a calibration certificate included?
The supplied page does not confirm inclusion of an individual calibration certificate. Specify documentation requirements when requesting a quotation.
