DITRON Digital Angle Protractors | Stainless Steel vs Fibreglass 200mm and 300mm Malaysia
Choosing a Digital Angle Protractor for Woodworking and Workshop Checks
DITRON Digital Angle Protractors measure the angle between two pivoting ruler arms. The supplied catalogue offers stainless steel and fibreglass versions in 200mm and 300mm sizes.
Both versions have a listed angular resolution of 0.05°, accuracy of ±0.3° and 360° measurement capability. Functions include data hold and reverse display.
For woodworking, furniture production and workshop teams in Malaysia, the main choices are ruler material, arm length and access to the surfaces being checked.
STAINLESS STEEL OR FIBREGLASS?
Stainless Steel Models
The JS-01 series uses stainless steel ruler arms. Choose this version when a metal ruler body suits the workshop task and handling preference.
Fibreglass Models
The JP-01 series uses a fibreglass ruler body. The catalogue lists black or white ruler body options.
Both material versions have the same listed angular resolution and accuracy. Material choice should therefore be based on the application rather than an assumed difference in measurement performance.

The catalogue’s inch size labels appear inconsistent with the stated metric lengths. Use the metric dimensions for initial selection and confirm the ruler markings when ordering.
KEY FEATURES
360° Angular Measurement
The pivoting arms provide 360° measurement capability for checking angles between suitable contact surfaces.
The catalogue separately states a maximum display value of 999.95°. This display limit should not be interpreted as the physical opening angle between the ruler arms.
Data Hold
The hold function retains the displayed reading for recording after a measurement.
Reverse Display
The reverse display function helps with reading orientation when the instrument is positioned differently. It does not replace the need to identify the correct angle on the workpiece.
CR2032 Battery
The catalogue specifies one CR2032 3V button cell.
Digital Head Colour Options
Red, black, blue and orange digital head options are listed. Confirm the preferred configuration when requesting a quotation.
200MM OR 300MM?
Choose 200mm for Shorter Contact Surfaces
The 200mm version may be easier to position where space is limited or the workpiece has shorter accessible edges.
Choose 300mm for Longer Contact Surfaces
The 300mm version provides longer ruler arms for contacting larger components.
A longer arm does not change the listed ±0.3° accuracy. The workpiece still needs straight, clean contact surfaces and sufficient clearance for both arms.
RESOLUTION IS DIFFERENT FROM ACCURACY
The 0.05° resolution describes the display increment. The stated angular accuracy is ±0.3°.
A reading displayed to 0.05° should not be interpreted as an angle verified within ±0.05°.
Assess whether the stated accuracy suits the cutting, assembly or inspection tolerance. Surface irregularity, incomplete seating and movement at the pivot can also affect the result.
TYPICAL APPLICATIONS
Woodworking Cutting Angle Checks
Check angles on suitable components during preparation and setup. Verify whether the machine requires the measured angle, its complement or another setting value.
Furniture Joint Inspection
Measure accessible joint angles where both ruler arms can seat against the intended reference surfaces.
Workshop Angle Comparison
Compare component angles during fabrication or assembly using a consistent contact method.
Layout and Fit-Up Checks
Check relationships between suitable straight edges before final assembly.
These applications are relevant to woodworking and manufacturing businesses in Selangor, Johor, Penang and other areas in Malaysia.
BASIC MEASUREMENT WORKFLOW
1. Clean the ruler edges and workpiece.
Remove sawdust, chips and residue that could prevent full contact.
2. Check the reference.
Follow the manufacturer’s procedure to establish or verify the starting reference.
3. Seat both arms.
Place each arm against the intended surface. Avoid bridging over burrs, rounded edges or uneven material.
4. Read the required angle.
Confirm that the reading corresponds to the dimension on the drawing or the angle needed for the task.
5. Use hold if required.
Retain the reading for recording, then release hold before taking another measurement.
6. Repeat the check.
Reposition the instrument to assess consistency before using the result for setup decisions.
FREQUENTLY ASKED QUESTIONS
What is the difference between JS-01 and JP-01?
JS-01 uses stainless steel ruler arms. JP-01 uses a fibreglass ruler body.
Which sizes are available?
Both versions are listed in 200mm and 300mm sizes.
What is the angular resolution?
The catalogue lists 0.05°.
What is the angular accuracy?
The listed accuracy is ±0.3° for all four models.
Does it measure 360°?
Yes. The catalogue specifies 360° measurement capability.
What battery does it use?
One CR2032 3V button cell is specified.
Does the hold function lock the arms?
Data hold retains the displayed reading. It should not be assumed to mechanically lock the ruler arms.
Can the reading be used directly as a saw setting?
That depends on the machine’s angle convention and the required cut. Check whether a conversion is needed before setting the machine.
