DITRON 301-150 Plastic Digital Caliper | 150mm General Measurement Malaysia
DITRON 301-150 Plastic Digital Caliper
The DITRON 301-150 is a 150mm plastic digital caliper for general dimensional checks. It supports outside, inside, step and depth measurement, with millimetre/inch conversion and zero-setting.
The catalogue lists a metric resolution of 0.1mm and accuracy of ±0.2mm. These specifications make it important to distinguish this model from higher-accuracy DITRON calipers when selecting an instrument.

MATERIAL DESCRIPTION TO CONFIRM
The page is titled Plastic Digital Caliper, and the Chinese description specifies a plastic housing and plastic ruler.
However, the English description states a plastic housing and 4Cr13 stainless steel ruler. These descriptions conflict.
Confirm the supplied beam and jaw materials before ordering if material construction is important to your application. The English material statement should not be treated as verified stainless steel construction.
GENERAL MEASUREMENT APPLICATIONS
The DITRON 301-150 can be considered for:
• Basic component size checks.
• Hobby and craft measurements.
• Educational demonstrations.
• General workshop comparisons.
• Checking dimensions where ±0.2mm accuracy meets the requirement.
For users in Selangor, Kuala Lumpur, Johor and Penang, selection should be based on the actual tolerance required.
This model’s stated accuracy should be assessed before using it for production acceptance or close-fitting mechanical components.
RESOLUTION AND ACCURACY
The metric resolution is 0.1mm. This describes the displayed increment.
The stated accuracy is ±0.2mm. A displayed reading is therefore not a guarantee that the actual dimension is within ±0.1mm.
For example, this model should not be selected solely because a drawing shows dimensions to one decimal place. The permitted tolerance and inspection procedure determine whether the instrument is suitable.
FOUR MEASUREMENT FUNCTIONS
Outside Measurement
Use the external jaws to check accessible dimensions such as width, thickness and outside diameter.
Inside Measurement
Use the internal jaws to check accessible internal dimensions. Align the jaws carefully with the feature.
Step Measurement
Use the step measuring faces to check suitable stepped features.
Depth Measurement
Use the depth rod to measure accessible holes and recesses. Keep the reference face seated correctly against the workpiece.
CONTROLS AND BATTERY OPERATION
The catalogue lists millimetre/inch conversion, ON/OFF and ZERO controls.
The ZERO function allows the display to be reset at a selected position. Check the reference before recording measurements.
The instrument uses an LR44 1.5V battery. Follow the supplied instructions for battery orientation and replacement.
Automatic power-on and automatic power-off after five minutes of inactivity are also listed.
301-150 VS HIGHER-ACCURACY DIGITAL CALIPERS
The DITRON 301-150 lists:
• 0.1mm metric resolution.
• ±0.2mm accuracy.
Several separately supplied DITRON 150mm digital caliper catalogue pages list:
• 0.01mm metric resolution.
• ±0.02mm accuracy.
These are materially different specifications. Choose the 301-150 for tasks that fit its stated capability. For tighter dimensional requirements, compare a suitable higher-accuracy instrument.
BASIC MEASURING PROCEDURE
1. Clean the measuring faces and workpiece.
2. Close the jaws gently and check zero.
3. Select millimetres or inches.
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 display.
8. Repeat the measurement to assess consistency.
Excessive force can affect readings, particularly with plastic measuring components.
CARE AND STORAGE
• Keep the jaws and sliding surfaces clean.
• Avoid impact, bending and excessive force.
• Do not use the caliper as a clamp or lever.
• Avoid measuring hot or moving components.
• Keep loose batteries away from children.
• Follow the manufacturer’s cleaning and storage instructions.
• Check performance against a suitable reference when measurement reliability matters.
The supplied page does not specify an IP protection rating, rechargeable operation or Bluetooth connectivity.
FREQUENTLY ASKED QUESTIONS
What is the measuring range?
The DITRON 301-150 has a listed range of 0–150mm.
What is the metric resolution?
The catalogue lists 0.1mm.
What accuracy is specified?
The listed accuracy is ±0.2mm.
Is it suitable for precision machining inspection?
Assess the required tolerance against ±0.2mm accuracy. Tighter inspection tasks may require a higher-accuracy caliper, micrometer or another measuring instrument.
Is the ruler plastic or stainless steel?
The Chinese text specifies plastic, while the English text states 4Cr13 stainless steel. Confirm the supplied construction before purchase.
What battery does it use?
The catalogue specifies an LR44 1.5V battery.
Is it rechargeable?
Rechargeable operation and Type-C charging are not listed.
Can it switch between millimetres and inches?
Yes. Millimetre/inch conversion is listed.
Can it measure depth?
Yes. Outside, inside, step and depth measurement are listed.
Is a calibration certificate included?
The supplied page does not confirm that an individual calibration certificate is included. Specify documentation requirements when requesting a quotation.
