DITRON 630 Digital Welding Seam Gauge & 631 Surface Difference Gauges Malaysia
DITRON Digital Welding Seam and Surface Difference Gauges
The DITRON 630 and 631 are specialised digital measuring instruments for different inspection tasks.
The 630-127 is a compact digital welding seam gauge with a listed 0–12.7mm measuring range and fixed angle templates. The 631 series is a surface difference gauge offered in 10mm, 20mm and 30mm ranges, with the manufacturer highlighting automotive lamp cover inspection.
Both products feature zero-setting at any position and millimetre/inch conversion.
DITRON 630-127 — DIGITAL WELDING SEAM GAUGE
The DITRON 630-127 is designed for welding seam dimensional checks. The catalogue describes measurement of flat and fillet weld features, subject to correct positioning and the supplied measuring procedure.
Its compact form makes it convenient to carry between inspection locations.
Product features:
• Digital welding seam measurement.
• Listed measuring range: 0–12.7mm.
• Catalogue-stated accuracy: ±0.03mm.
• Fixed angle templates: 60°, 70°, 80° and 90°.
• Zero-setting at any position.
• Millimetre/inch conversion at any position.
• Compact, portable design.
The fixed angle templates provide reference profiles. The catalogue does not specify electronic angle measurement or an angular accuracy value.
WELDING MEASUREMENT SELECTION
Before selecting the 630-127, identify the exact dimension required by the inspection procedure.
Weld reinforcement height, fillet leg length and throat thickness are different characteristics. Confirm which measurements the supplied gauge geometry and instructions support.
A weld dimensional reading alone does not establish weld acceptance. Results must be assessed against the applicable drawing and inspection requirements.
DITRON 631 SERIES — DIGITAL SURFACE DIFFERENCE GAUGES
The DITRON 631 series is designed for surface difference measurement. The catalogue specifically highlights use on automotive lamp covers.
The measuring arrangement establishes contact with a reference surface and a second measuring location. Correct positioning is essential when checking the difference between adjacent surfaces.
Product features:
• Digital surface difference measurement.
• Compact measuring arrangement.
• Zero-setting at any position.
• Relative measurement using a selected reference.
• Millimetre/inch conversion at any position.
• Three listed measuring ranges.

630 VS 631 — DIFFERENT INSPECTION TASKS
Choose the 630-127 when the application requires welding seam dimensional checks using the illustrated contact arrangement and angle templates.
Choose a 631 model when the application requires a surface height difference check and its reference foot and probe can access the intended locations.
These products are not interchangeable simply because both have digital displays. Their measuring contacts and reference arrangements serve different purposes.
APPLICATIONS IN MALAYSIA
The DITRON 630-127 can be considered for:
• Fabrication workshop weld dimensional checks.
• Welding training demonstrations.
• Maintenance fabrication inspection.
• Recording supported weld dimensions under an established inspection procedure.
The DITRON 631 series can be considered for:
• Automotive lamp cover surface difference checks.
• Assembly surface alignment assessment.
• Comparison of accessible adjacent surface heights.
• Component inspection where the contact geometry matches the feature.
For users in Selangor, Kuala Lumpur, Johor and Penang, a component drawing or clear application photo can help assess instrument suitability.
ZERO-SETTING AND UNIT CONVERSION
Both products list zero-setting at any position.
A selected reference can be used for comparative measurements, following the operating instructions. Check the reference before recording results, particularly after repositioning the instrument.
Both also support millimetre/inch conversion.
The catalogue’s wording about relative and absolute measurement conversion does not explicitly establish a coded absolute encoder or reference retention after power loss.
ACCURACY AND DISPLAY RESOLUTION
Catalogue-stated accuracy:
630-127: ±0.03mm
631-010: ±0.02mm
631-020: ±0.02mm
631-030: ±0.02mm
The supplied page does not explicitly state display resolution. Confirm this separately rather than inferring it from the product photographs.
Accuracy also depends on reference positioning, cleanliness, contact force and instrument alignment.
BASIC MEASURING PROCEDURE — 630-127
1. Identify the weld dimension required by the inspection procedure.
2. Allow the workpiece to cool before contact measurement.
3. Remove loose spatter and contamination from the reference locations.
4. Check the gauge reference according to the instructions.
5. Select the appropriate measuring surface or angle template.
6. Position the gauge without rocking or forcing it.
7. Read and record the supported dimension.
8. Repeat at the locations required by the inspection plan.
BASIC MEASURING PROCEDURE — 631 SERIES
1. Identify the reference surface and comparison surface.
2. Clean both contact locations.
3. Establish zero using the manufacturer’s procedure.
4. Seat the reference foot securely.
5. Bring the probe gently into contact with the comparison surface.
6. Keep the instrument correctly aligned.
7. Read the surface difference.
8. Repeat the measurement to assess consistency.
For plastic lamp covers or other flexible parts, avoid contact force that could deform the component.
CARE AND BASIC CHECKS
• Keep measuring contacts and reference surfaces clean.
• Protect projecting probes and templates from impact.
• Avoid excessive measuring force.
• Do not measure hot or moving components.
• Follow the supplied battery and cleaning instructions.
• Store with the contact surfaces protected.
• Check performance against suitable reference standards according to your quality procedure.
The supplied page does not explicitly specify battery type, rechargeable operation, Bluetooth capability or an IP protection rating.
