Mitutoyo 505-731 Dial Calipers 0 - 200 mm, Graduation 0.02 mm, 2 mm/rev
Part No. 505-731 | Range 0–200 mm | Graduation 0.02 mm | Accuracy ±0.03 mm
Product Overview
The Mitutoyo 505-731 is a mechanical Series 505 dial caliper with a 0–200 mm measuring range, 0.02 mm graduation and ±0.03 mm accuracy. It is designed for general-purpose metric dimensional measurement where a clear analog dial and battery-free operation are preferred.
The redesigned Series 505 dial movement provides smooth slider operation and high shock protection for regular workshop use. Its mechanical dial provides a direct reading without batteries or electronic components.
On this model, one complete dial revolution represents 2 mm of measuring range, while each dial graduation represents 0.02 mm. This configuration allows faster jaw travel across the 200 mm range while retaining a clear mechanical indication for dimensional measurement.
The hardened stainless steel beam and standard hardened stainless steel jaws allow the caliper to measure outside dimensions, inside dimensions, depths and steps with one instrument. Bezel and slider lock screws help retain the dial and jaw positions when a measurement needs to be checked or transferred away from the workpiece.
The 0–200 mm range makes the 505-731 suitable for general machining, fabrication, maintenance and incoming inspection. When measuring larger features near the end of the range, keep the beam square to the workpiece and use appropriate support for consistent measurement technique.
For a smaller metric range, the Mitutoyo 505-730 covers 0–150 mm.

Who This Product Is Best For
The Mitutoyo 505-731 is suited to machinists, quality inspectors, maintenance technicians, fabrication teams and workshop personnel who need a metric dial caliper covering dimensions up to 200 mm.
Its four measurement functions make it useful for checking outside dimensions, inside dimensions, depths and steps with one instrument. The mechanical dial is also useful where a battery-free measuring tool is preferred.
The 2 mm per revolution configuration provides faster jaw travel across the measuring range than a 1 mm per revolution model. This can be useful when repeatedly measuring components across a broad portion of the 200 mm capacity.
For finer dial travel per revolution, the 505-733 uses 1 mm per revolution and 0.01 mm graduation. For larger components, the 505-745 provides a 0–300 mm range.
How to Use
-
Clean the measuring jaws and workpiece before measurement.
-
Close the jaws gently and check the dial zero. Adjust the bezel if required and secure the bezel lock.
-
Open the jaws beyond the dimension being measured and position them around, inside or against the feature.
-
Close the jaws gently using the slider until the measuring surfaces contact the workpiece without excessive force.
-
Read the beam and dial indication according to the 0.02 mm graduation.
-
Keep the beam properly aligned with the measured feature, particularly when working near the full 200 mm range.
-
Use the slider lock when the measurement needs to be retained while removing the caliper from the part.
-
Clean the instrument after use and store it in the supplied fitted case.
For critical inspection applications, verify the caliper against a suitable reference standard and follow the applicable calibration procedure.
Frequently Asked Questions
What can the Mitutoyo 505-731 measure?
The 505-731 measures outside dimensions, inside dimensions, depths and steps across its 0–200 mm measuring range.
What is the graduation of the Mitutoyo 505-731?
The dial graduation is 0.02 mm. One complete dial revolution represents 2 mm of measuring range.
How accurate is the Mitutoyo 505-731?
The specified accuracy for the 505-731 is ±0.03 mm.
Does the Mitutoyo 505-731 require batteries?
No. The 505-731 is a mechanical dial caliper and operates without batteries.
What type of jaws does the 505-731 have?
The 505-731 uses standard hardened stainless steel jaws and is intended as a general-purpose metric Series 505 configuration.
What is the difference between the 505-731 and 505-733?
Both models cover 0–200 mm and use standard hardened stainless steel jaws with ±0.03 mm specified accuracy. The 505-731 has 0.02 mm graduation and 2 mm per revolution, while the 505-733 has 0.01 mm graduation and 1 mm per revolution.
What is the difference between the 505-731 and 505-682?
The supplied specifications identify both models with a 0–200 mm range, standard jaws, 0.01 mm graduation and 1 mm per revolution for the 505-682, while the 505-731 uses 0.02 mm graduation and 2 mm per revolution. The 505-682 is also an earlier order number, so current availability and order-number status should be confirmed before substitution.
What is the difference between the 505-731 and 505-745?
The 505-731 covers 0–200 mm, while the 505-745 covers 0–300 mm. The 505-731 has 0.02 mm graduation and ±0.03 mm accuracy; the 505-745 uses the same 0.02 mm graduation and ±0.04 mm accuracy.
Is the Mitutoyo 505-731 a digital caliper?
No. The 505-731 is an analog mechanical dial caliper. It does not require batteries and provides readings through its mechanical dial.
