DITRON 622 Adjustable Jaw & 624 Duckbill Digital Calipers | Special Measurement Malaysia
DITRON 622 and 624 Specialised Digital Calipers
The DITRON 622 and 624 series provide different jaw arrangements for components that are difficult to measure with conventional calipers.
The 622 series features a vertically adjustable main-scale jaw for measuring suitable surfaces at different heights. The 624 series features broad duckbill measuring faces, with catalogue applications including steel wire ropes and relatively soft materials such as rubber and sponge.
Both series are available in 150mm, 200mm and 300mm measuring ranges.
PRODUCT HIGHLIGHTS
• 622 series: vertically adjustable main-scale jaw.
• 624 series: broad duckbill measuring faces.
• Digital readout.
• Zero-setting at any position.
• Relative measurement using a selected reference.
• Millimetre/inch conversion at any position.
• Three measuring ranges for each series.
622 SERIES — ADJUSTABLE JAW DIGITAL CALIPERS
The DITRON 622 series allows the main-scale jaw to slide up and down. This arrangement can help position the contacts against suitable measuring surfaces that are not at the same height.
Although the English catalogue heading says “Exchangeable Jaws,” the accompanying description specifically identifies vertical jaw adjustment. It does not establish that interchangeable jaw sets are supplied.

ADJUSTABLE JAW APPLICATIONS
The 622 can be considered where a conventional fixed jaw arrangement cannot contact both required surfaces correctly.
Before selecting, check:
• The dimension to be measured.
• Height difference between the contact locations.
• Required jaw adjustment.
• Clearance around shoulders and recesses.
• The manufacturer’s reference-setting procedure.
The supplied page does not state the usable vertical adjustment travel separately. Do not treat dimension a as the adjustment travel.
624 SERIES — DUCKBILL DIGITAL CALIPERS
The DITRON 624 series uses broad measuring faces to span a larger contact area.
The catalogue highlights workpieces such as steel wire ropes and relatively soft surfaces such as rubber and sponge. Application suitability depends on contact positioning and the measuring force used.
Available models:
DITRON 624-150
Listed measuring range: 0–150mm
Catalogue-stated accuracy: ±0.04mm
Dimension L: 250mm
Dimension a: 50mm
Dimension b: 36mm
Dimension c: 40mm
Dimension d: 16mm
DITRON 624-200
Listed measuring range: 0–200mm
Catalogue-stated accuracy: ±0.04mm
Dimension L: 300mm
Dimension a: 50mm
Dimension b: 36mm

Dimension d: 16mm
DITRON 624-300

Dimension L: 400mm
Dimension a: 50mm
Dimension b: 36mm
Dimension c: 40mm
Dimension d: 16mm
Dimensions correspond to the manufacturer’s drawing. The supplied page does not list a numerical value for dimension k.
MEASURING SOFT MATERIALS
Broad contacts can distribute force over a larger area, but rubber and sponge may still compress during measurement.
The catalogue does not specify a constant-force mechanism or controlled contact pressure. Results on compressible materials therefore depend on the measuring method and applied force.
If your inspection procedure specifies contact pressure, dwell time or contact area, confirm that the instrument and method meet those requirements.
STEEL WIRE ROPE MEASUREMENT
The 624 catalogue identifies steel wire ropes as an application.
Position the broad faces according to the applicable inspection procedure so they contact the intended rope surfaces. Rope construction, orientation and local irregularities can affect readings.
A diameter reading alone does not establish the overall condition or suitability of a wire rope.
622 VS 624 — WHICH SHOULD YOU CHOOSE?
Choose the 622 series when vertical jaw adjustment is needed to reach the intended measuring surfaces.
Choose the 624 series when broad measuring faces are needed to span the workpiece or provide a larger contact area.
Both series have the same catalogue-stated accuracy at corresponding ranges. Their main difference is contact geometry.
CHOOSING THE MEASURING RANGE
150mm Models
For components within a 150mm measuring capacity.
200mm Models
For dimensions exceeding a 150mm range.
300mm Models
For larger dimensions requiring up to 300mm capacity.
Maximum range does not guarantee access. Check the full contact arrangement against the workpiece drawing.
ZERO-SETTING AND UNIT CONVERSION
Both series list zero-setting at any position and millimetre/inch conversion.
For the 622, verify the reference after adjusting and securing the jaw. Follow the manufacturer’s procedure before recording measurements.
The catalogue’s wording about relative and absolute measurement conversion does not explicitly establish a coded absolute encoder or reference retention after power loss.
APPLICATIONS IN MALAYSIA
The DITRON 622 can be considered for:
• Offset measuring surfaces.
• Components with different contact heights.
• Suitable recessed or stepped external features.
• Maintenance and replacement-part comparison.
The DITRON 624 can be considered for:
• Suitable steel wire rope diameter checks.
• Rubber component measurements.
• Sponge or foam comparisons under a defined method.
• Workpieces requiring broad contact faces.
For workshops and inspection departments in Selangor, Kuala Lumpur, Johor and Penang, provide the component geometry, material and tolerance when selecting.
ACCURACY AND DISPLAY RESOLUTION
Catalogue-stated accuracy for both series:
150mm models: ±0.04mm
200mm models: ±0.04mm
300mm models: ±0.05mm
The supplied page does not explicitly specify display resolution. Confirm this separately.
Instrument accuracy does not account for every application effect. Soft-material compression, contact alignment and reference positioning can introduce additional variation.
BASIC MEASURING PROCEDURE
1. Identify the required dimension and contact locations.
2. Clean the measuring faces and workpiece.
3. For the 622, adjust and secure the jaw according to the instructions.
4. Establish or verify the measuring reference.
5. Position the contacts correctly.
6. Apply light, consistent measuring force.
7. Check alignment and read the display.
8. Repeat the measurement to assess consistency.
For soft materials, use a defined procedure to control compression and improve comparability.
CARE AND BASIC CHECKS
• Protect specialised jaws from impact and bending.
• Keep contact faces and sliding surfaces clean.
• Avoid excessive measuring force.
• Do not use the jaws as levers or clamps.
• Avoid measuring hot or moving components.
• Follow the supplied battery and cleaning instructions.
• Check performance against suitable reference standards according to your quality procedure.
The supplied page does not explicitly specify battery type, rechargeable operation, Bluetooth capability, IP rating or material grade.
