DITRON 451 & 613 Digital Depth Calipers | Compact and Thin Rod Depth Gauges Malaysia
DITRON 451 and 613 Digital Depth Calipers
The DITRON 451 compact digital depth caliper and 613 thin rod digital depth caliper are designed for depth and step measurements.
The 451 provides a compact 0–25mm measuring range with optional flat or round rod probes. The 613 series provides thin rod configurations with measuring ranges from 0–30mm to 0–300mm.
For workshops, mould makers and inspection departments in Malaysia, selection should consider measuring depth, hole access, probe geometry and the available reference surface.
DITRON 451 — COMPACT DIGITAL DEPTH CALIPER
The DITRON 451 is described in the catalogue for measuring screw holes, small mould holes, workpiece holes, tyre wear and step height, where the probe and reference base can be positioned correctly.
Its compact measuring range suits shallow features. Confirm the supplied probe configuration before ordering.
Product features:
• Measuring range: 0–25mm / 1in, as listed in the catalogue.
• Resolution: 0.01mm / 0.0005in.
• Catalogue-stated accuracy: ±0.02mm.
• Plastic display housing.
• 4Cr13 stainless steel ruler.
• CR2032 3V battery.
• Automatic power-on.
• Automatic power-off after five minutes of inactivity.
• Optional flat probe or round rod probe.
Catalogue drawing dimensions:
Dimension a: 59.5mm
Dimension e: 27mm
The catalogue rounds the imperial range to 1in. Confirm the exact usable travel if your application requires a full 25.4mm.
DITRON 613 — THIN ROD DIGITAL DEPTH CALIPERS
The DITRON 613 series uses a thin rod measuring arrangement for accessible small holes and depth features.
The catalogue drawing indicates a Φ3mm probe and a 100mm base dimension a. Confirm the probe specification and clearance against the intended workpiece before ordering.
Product features:
• Depth and step measurement.
• Thin rod probe.
• Zero-setting at any position.
• Relative measurement using a selected reference.
• Millimetre/inch conversion at any position.
• Six listed measuring ranges.

451 VS 613 — WHICH SHOULD YOU CHOOSE?
Choose the DITRON 451 when you require:
• A compact instrument for shallow measurements.
• A 0–25mm measuring range.
• A choice of flat or round rod probe configuration.
• Explicitly listed CR2032 battery operation.
Choose the DITRON 613 when you require:
• A thin rod measuring arrangement.
• More measuring capacity, up to 300mm.
• A listed 100mm base dimension.
• Zero-setting for comparative measurements.
Select according to the actual feature geometry. A longer range does not automatically provide better access or higher accuracy.
CHECKING HOLE AND PROBE ACCESS
Before ordering, confirm:
• Hole opening diameter or slot width.
• Required measuring depth.
• Internal obstructions.
• Flatness and width of the reference surface.
• Bottom shape of the hole or recess.
• Probe diameter or flat probe dimensions.
• Required tolerance.
A probe must enter freely and contact the intended surface. Nominal probe diameter alone does not establish the minimum usable hole size.
REFERENCE BASE AND MEASUREMENT ALIGNMENT
A depth caliper measures from the surface supporting its base to the surface contacted by its probe.
The base must sit securely on the intended reference surface. Burrs, chips, curved surfaces or rocking of the base can affect the reading.
For drilled holes, define whether the required depth refers to the drill-point bottom or the full-diameter portion. Probe shape and contact location can produce different results.
ZERO-SETTING AND COMPARATIVE MEASUREMENT
The 613 series lists zero-setting at any position. This allows a reference to be established for checking dimensional differences, following the operating instructions.
The catalogue’s wording about relative and absolute measurement conversion does not explicitly establish a coded absolute encoder or reference retention after power loss.
Do not transfer this function claim to the 451 unless confirmed by its operating instructions.
APPLICATIONS IN MALAYSIA
These depth calipers can be considered for:
• Screw hole depth checks.
• Small mould feature inspection.
• Workpiece recess measurements.
• Step height checks.
• Maintenance and replacement-part assessment.
• Accessible tyre tread groove checks using a suitable 451 probe.
For workshops and inspection teams in Selangor, Kuala Lumpur, Johor and Penang, choose the model according to the required depth and contact geometry.
For tight-tolerance measurements, assess whether a depth micrometer or another measuring system is more appropriate.
BASIC MEASURING PROCEDURE
1. Clean the reference surface and measuring probe.
2. Check that the probe suits the feature.
3. Establish zero according to the operating instructions.
4. Seat the base securely on the reference surface.
5. Advance the probe gently to the intended measuring surface.
6. Keep the instrument correctly aligned.
7. Apply light, consistent contact force.
8. Read the display.
9. Repeat the measurement to assess consistency.
Do not force a thin probe into an obstructed hole or use it to clear debris.
CARE AND BASIC CHECKS
• Protect the probe from bending and impact.
• Keep the base contact face clean.
• Remove chips before measurement.
• Avoid measuring hot or moving components.
• Follow the supplied battery replacement instructions.
• Store with the measuring probe protected.
• Check performance against suitable reference standards according to your quality procedure.
The supplied page does not explicitly specify rechargeable operation, Bluetooth capability or an IP protection rating for either product.
