DITRON 201 & 202 Series Dial Calipers | 150mm, 200mm & 300mm Stainless Steel Malaysia
DITRON 201 and 202 Series Dial Calipers
The DITRON 201 and 202 series provide mechanical dimensional measurement using a beam scale and dial readout. Both series feature stainless steel construction and a manufacturer-described double-way shock-protection design.
The main difference is the dial graduation. The 201 series has 0.01mm graduations, while the 202 series has 0.02mm graduations. Both offer 150mm, 200mm and 300mm measuring ranges.
For workshops and inspection departments in Malaysia, select according to measuring capacity, graduation preference and required accuracy.

201 VS 202 — WHICH SERIES SHOULD YOU CHOOSE?
Choose the 201 series when your measuring procedure or reading preference calls for 0.01mm dial graduations.
Choose the 202 series when 0.02mm dial graduations meet the task.
A finer graduation does not automatically mean better accuracy. The manufacturer lists the same accuracy for both series at corresponding measuring ranges.
CHOOSING THE MEASURING RANGE
150mm Models
For smaller components and routine dimensional checks within a 150mm capacity.
200mm Models
For components requiring more opening capacity than a 150mm model.
300mm Models
For larger components requiring up to 300mm capacity. Check jaw reach and access around the workpiece before selecting.

DOUBLE-WAY SHOCK PROTECTION
The catalogue describes a double-way shock-protection design intended to help protect accuracy and stability.
This feature should not be interpreted as a guarantee that the caliper can withstand drops or impact without damage. Check zero and measuring performance after an accidental knock, drop or unusual slider movement.
Keep the rack and sliding surfaces free from chips and contamination.
FOUR MEASUREMENT FUNCTIONS
Outside Measurement
Use the external jaws to check accessible dimensions such as thickness, width 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 and recesses. Seat the reference face correctly against the workpiece.
READING A DIAL CALIPER
A measurement combines the beam scale reading with the dial indication.
Use the graduation specified for the selected series:
• 201: 0.01mm per dial division.
• 202: 0.02mm per dial division.
Confirm the dial’s full-revolution value from the instrument markings or operating instructions. Do not assume the same value for both series.
DIAL CALIPER VS DIGITAL CALIPER
A dial caliper provides a mechanical readout without batteries. Users read the beam scale and dial together.
A digital caliper provides a direct numerical display and may offer unit conversion or other functions, depending on the model.
Choose according to the required specification, working conditions and operator preference. Neither readout type is automatically more accurate.
APPLICATIONS IN MALAYSIA
The DITRON 201 and 202 series can be considered for:
• General workshop measurements.
• Machining and fabrication checks.
• Incoming component inspection.
• Maintenance and spare-part measurement.
• Production and assembly checks.
• Technical training in mechanical measurement.
For workshops and inspection teams in Selangor, Kuala Lumpur, Johor and Penang, compare the instrument’s stated accuracy with the workpiece tolerance.
For close-tolerance inspection, assess whether a micrometer or another measuring instrument is more appropriate.
GRADUATION AND ACCURACY
Dial graduation describes the reading interval. Accuracy describes the stated measuring performance.
For example, the 201-150 has a 0.01mm graduation and ±0.02mm catalogue-stated accuracy. Its finer dial divisions do not establish ±0.01mm accuracy.
Measuring force, cleanliness, temperature, alignment and instrument condition also affect results.
BASIC MEASURING PROCEDURE
1. Clean the measuring faces and workpiece.
2. Close the jaws gently and check zero.
3. Confirm smooth slider movement.
4. Position the appropriate measuring faces.
5. Apply light, consistent contact force.
6. Keep the instrument aligned with the dimension being measured.
7. Read the beam scale and dial together.
8. Repeat the measurement to assess consistency.
9. Recheck zero after use.
If zero does not repeat or the pointer behaves irregularly, inspect the instrument before relying on its readings.
CARE AND STORAGE
• Keep the rack and sliding surfaces clean.
• Remove chips before closing the jaws.
• Avoid impact and excessive measuring force.
• Do not use the jaws as levers or clamps.
• Avoid measuring hot or moving components.
• Clean and dry the instrument after use.
• Follow the manufacturer’s maintenance instructions.
• Check performance against suitable reference standards according to your quality procedure.
The supplied page does not state an IP protection rating or a specific stainless steel grade.
FREQUENTLY ASKED QUESTIONS
What is the main difference between the 201 and 202?
The 201 has 0.01mm dial graduations. The 202 has 0.02mm dial graduations.
Is the 201 more accurate?
The catalogue lists the same accuracy for corresponding measuring ranges.
Do these calipers require batteries?
No. They use mechanical beam scales and dial readouts.
What measuring ranges are available?
Both series list 150mm, 200mm and 300mm models.
Are they made from stainless steel?
Yes. Stainless steel material is specified, but the exact grade is not listed.
Does shock protection make them drop-proof?
No drop-proof performance is established on the supplied page. Handle them as precision measuring instruments.
Can they measure depth?
Yes. Outside, inside, step and depth measurement are listed.
Can they switch between millimetres and inches?
Electronic unit conversion is not applicable. These models are listed with metric dial graduations; confirm any alternative scale configuration separately.
What should I do if the pointer does not return to zero?
Check cleanliness and repeat the closed-jaw check. If the problem continues, arrange inspection rather than relying on the readings.
Is a calibration certificate included?
The DIN 862 marking shown in the catalogue does not establish that an individual calibration certificate is included. Specify documentation requirements when requesting a quotation.
