DITRON 612 Series Large Range Digital Calipers | 300mm to 1000mm with Fine Adjustment Malaysia
DITRON 612 Series Digital Calipers with Standard Jaws
The DITRON 612 series provides large-range digital measurement with extended lower jaws, upper inside measuring jaws and a fine-adjustment carriage.
Available in measuring ranges from 0–300mm to 0–1000mm, the series supports large outside and inside dimensional checks. Different lower jaw lengths help users select an instrument that can reach the intended measuring surfaces.
For engineering workshops, fabrication facilities and inspection departments in Malaysia, selection should consider measuring capacity, jaw reach, workpiece access and required accuracy.

CHOOSING THE MEASURING RANGE
300mm Models
Available with 90mm or 100mm lower jaw dimensions.
500mm and 600mm Models
Available with 100mm or 150mm lower jaw dimensions.
800mm and 1000mm Models
Listed with a 150mm lower jaw dimension and larger upper-jaw-related dimensions than the smaller models.
Choose a range that accommodates the largest dimension being measured. Then check that the jaws can reach the required contact surfaces without interference.
WHY JAW LENGTH MATTERS
Longer jaws can reach measuring surfaces set back from a component edge.
However, jaw dimension a is not a guaranteed usable recess depth. Jaw shape, surrounding shoulders and component clearance also affect access.
Longer jaws do not automatically provide higher accuracy. For example:
Lower jaw dimension a: 100mm
Catalogue-stated accuracy: ±0.05mm
Lower jaw dimension a: 150mm
Catalogue-stated accuracy: ±0.06mm
Select the required reach while checking the accuracy of the exact model.
OUTSIDE AND INSIDE MEASUREMENT
Outside Measurement
Use the lower jaws to check accessible external dimensions such as component width and outside diameter.
Recessed Feature Measurement
The catalogue describes extended lower knife-edge jaws for measuring suitable recessed features. Confirm contact access against the workpiece drawing.
Inside Measurement
Use the upper inside jaws to check accessible internal dimensions. Confirm the minimum measurable opening and correct measuring procedure before use.
Depth and step measurement functions are not specified on this catalogue page.
FINE-ADJUSTMENT CARRIAGE
The manufacturer lists a fine-adjustment carriage for controlled slider positioning.
This can help users approach the measuring surface gradually. It does not provide a specified constant measuring force or improve the instrument’s stated accuracy.
Apply light, consistent contact force and avoid forcing the jaws against the component.
ZERO-SETTING AND PRESET FUNCTIONS
Zero-setting at any position allows users to establish a reference for comparative measurements.
The preset function allows a reading to be assigned at a selected position, following the operating instructions. Confirm the preset value and measuring reference before recording results.
These functions should not be treated as confirmation of a coded absolute encoder or position retention after battery removal. Those capabilities are not specified on the supplied page.
MILLIMETRE AND INCH CONVERSION
The catalogue lists millimetre/inch conversion at any position.
This supports measurement tasks involving metric and imperial dimensions. Changing the displayed unit does not change measurement accuracy.
APPLICATIONS IN MALAYSIA
The DITRON 612 series can be considered for:
• Large machined component inspection.
• Fabrication workshop dimensional checks.
• Accessible flange and housing measurements.
• Ring and frame measurements.
• Maintenance and replacement-part assessment.
• Incoming inspection of larger components.
For workshops and factories in Selangor, Kuala Lumpur, Johor and Penang, provide the required measuring dimension, tolerance and component drawing when selecting a model.
For close-tolerance work, assess whether a micrometer, bore measuring instrument or another measuring system is more appropriate.
ACCURACY AND MEASUREMENT CONDITIONS
Catalogue-stated accuracy ranges from ±0.04mm to ±0.07mm across the listed models.
Large-range measurement requires careful support and alignment. Beam deflection, excessive force, temperature differences and contamination at the measuring faces can affect results.
Use the specification for the exact model. Do not infer accuracy from the number of decimal places shown in the product photograph.
BASIC MEASURING PROCEDURE
1. Clean the measuring faces and workpiece.
2. Check slider movement and the measuring reference.
3. Confirm whether zero or a preset value is active.
4. Support the instrument and workpiece securely.
5. Position the appropriate jaws against the measuring surfaces.
6. Use the fine-adjustment carriage according to the instructions.
7. Apply light, consistent contact force.
8. Check alignment and read the display.
9. Repeat the measurement to assess consistency.
Avoid using the long jaws as levers or clamps.
CARE AND BASIC CHECKS
• Keep the beam and sliding surfaces clean.
• Remove chips before closing the jaws.
• Protect long jaws from impact and excessive force.
• Avoid measuring hot or moving components.
• Follow the supplied battery and cleaning instructions.
• Store with adequate support for the beam and jaws.
• Check performance against suitable reference standards according to your quality procedure.
The supplied page does not explicitly state an IP rating, battery type, rechargeable capability, Bluetooth function or material grade. Confirm these details separately if required.
