DITRON 402 & 404 Series Universal Digital Calipers | 150mm, 200mm & 300mm Malaysia
DITRON 402 and 404 Series Universal Digital Calipers
The DITRON 402 and 404 series provide digital readings for outside, inside, step and depth measurement. Both series are available in 150mm, 200mm and 300mm measuring ranges, with a resolution of 0.01mm / 0.0005in.
The 402 series features a screw-secured battery cover and is explicitly listed with a 3V battery. The 404 series offers an alternative display housing design with the same catalogue-stated measuring ranges and accuracy.
These universal digital calipers can be considered for routine dimensional checks in Malaysian workshops, maintenance departments and component inspection areas.

402 SERIES — SCREW-SECURED BATTERY COVER
The DITRON 402 series features a plastic display housing and a 4Cr13 stainless steel ruler.
Its battery cover is secured with a screw. The manufacturer describes this design as helping prevent children from opening the compartment and accidentally swallowing the battery.
The secured cover is a battery-access precaution. Keep the instrument and loose batteries away from children, and refit the cover correctly after battery replacement.

402 VS 404 — SELECTION POINTS
The 402 series specifically lists:
• Plastic display housing.
• Screw-secured battery cover.
• 3V battery.
The 404 series:
• Offers a different display housing design.
• Has the same catalogue-stated accuracy at corresponding ranges.
• Requires confirmation of housing material and battery specifications.
The supplied page does not establish that either series is more accurate than the other.
CHOOSING THE MEASURING RANGE
150mm Models
Suitable for smaller components, fasteners and general dimensional checks within a 150mm capacity.
200mm Models
Provide additional opening capacity for components that exceed a 150mm measuring range.
300mm Models
Provide up to 300mm measuring capacity for larger workpieces. Check jaw reach and access around the component before selecting.
Choose according to the largest dimension being measured and the required accuracy. A longer range does not mean higher accuracy.
FOUR MEASUREMENT FUNCTIONS
Outside Measurement
Use the external jaws to check accessible external dimensions, including width, thickness and outside diameter.
Inside Measurement
Use the internal jaws to check accessible internal dimensions. Correct alignment is important for consistent readings.
Step Measurement
Use the step measuring faces to check suitable stepped features.
Depth Measurement
Use the depth rod to measure accessible holes or recesses. Keep the reference face correctly seated against the workpiece.
APPLICATIONS IN MALAYSIA
The DITRON 402 and 404 series can be considered for:
• General workshop measurements.
• Incoming component inspection.
• Machining and fabrication checks.
• Maintenance and spare-part measurements.
• Assembly dimensional checks.
• Supervised technical training.
For users in Selangor, Kuala Lumpur, Johor and Penang, selection should consider the workpiece dimensions, required tolerance and measuring environment.
For tight-tolerance work, assess whether a micrometer or another measuring instrument is more appropriate.
RESOLUTION AND ACCURACY
The 0.01mm metric resolution describes the displayed increment. It does not mean the instrument has ±0.01mm accuracy.
Catalogue-stated accuracy for both series:
0–150mm: ±0.02mm
0–200mm: ±0.03mm
0–300mm: ±0.04mm
Cleanliness, temperature, jaw alignment, measuring force and instrument condition also influence measurement results.
AUTOMATIC POWER FUNCTIONS
Both series are listed with automatic power-on and automatic power-off after five minutes of inactivity.
The supplied page does not specify battery runtime. For the 402 series, a 3V battery is listed, but the exact battery code should be confirmed before replacement. Battery voltage alone is not sufficient to identify the correct replacement.
CARE AND BASIC CHECKS
• Clean the measuring faces and workpiece before use.
• Close the jaws gently and check the zero reading.
• Use light, consistent measuring force.
• Keep the caliper aligned with the dimension being measured.
• Avoid measuring hot or moving components.
• Keep the battery compartment correctly closed.
• Check performance against suitable reference standards according to your quality procedure.
• Follow the supplied cleaning and storage instructions.
The supplied catalogue page does not list an IP protection rating. Confirm environmental suitability before use around water, coolant or heavy contamination.
FREQUENTLY ASKED QUESTIONS
