Mitutoyo 505-745 Dial Caliper 0 - 300 mm, Graduation 0.02 mm, 2 mm/rev
Part No. 505-745 | Range 0–300 mm | Graduation 0.02 mm | Accuracy ±0.04 mm
Product Overview
The Mitutoyo 505-745 is a mechanical Series 505 dial caliper with a 0–300 mm measuring range, 0.02 mm graduation and ±0.04 mm accuracy. It is designed for general dimensional measurement where a larger metric range and battery-free mechanical operation are required.
The redesigned Series 505 dial movement provides smooth slider operation and high shock protection for regular workshop use. The analog dial provides a direct mechanical reading without batteries or electronic components.
The 505-745 has a measuring range of 2 mm per dial revolution, with each dial graduation representing 0.02 mm. This configuration provides straightforward indication across the long 300 mm measuring range while retaining fine dial resolution.
Its hardened stainless steel beam and standard hardened stainless steel jaws allow outside dimensions, inside dimensions, depths and steps to be measured with one instrument. Bezel and slider lock screws help retain the dial and jaw positions when a reading needs to be checked or transferred away from the workpiece.
The 300 mm range makes this model suitable for larger components such as flanges, housings, plates and fabricated parts. For measurements at full reach, keeping the beam square to the feature and supporting the caliper appropriately can help maintain consistent measurement technique.
For a smaller metric range, the Mitutoyo 505-731 covers 0–200 mm.

Who This Product Is Best For
The Mitutoyo 505-745 is suited to machinists, quality inspectors, maintenance technicians, fabrication teams and workshop personnel who need a metric dial caliper covering measurements up to 300 mm.
Its extended range is useful for larger workpieces that exceed the capacity of many standard calipers. The four measurement functions allow the same instrument to be used for checking outside dimensions, inside dimensions, depths and steps.
The battery-free mechanical design can also be useful in workshop environments where measuring instruments are regularly exposed to coolant, oil or other shop-floor contaminants.
For smaller components, a shorter-range Series 505 model may be easier to handle. The 505-731, for example, covers 0–200 mm.
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 feature, particularly when measuring near the full 300 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 505-745 measure?
The 505-745 measures outside dimensions, inside dimensions, depths and steps across its 0–300 mm measuring range.
What is the graduation of the Mitutoyo 505-745?
The dial graduation is 0.02 mm. One complete dial revolution represents 2 mm of measuring range.
How accurate is the Mitutoyo 505-745?
The specified accuracy for the 505-745 is ±0.04 mm.
Does the Mitutoyo 505-745 require batteries?
No. The 505-745 is a mechanical dial caliper and operates without batteries.
What type of jaws does the 505-745 have?
The 505-745 uses standard hardened stainless steel jaws and is intended as a general-purpose metric Series 505 configuration.
What is the difference between the 505-745 and 505-731?
The main difference is measuring range. The 505-745 covers 0–300 mm, while the 505-731 covers 0–200 mm. Choose the range that comfortably covers the largest dimensions you need to measure.
Is the 505-745 suitable for large components?
Its 0–300 mm range makes it suitable for measuring larger components such as flanges, housings, plates and fabricated parts, provided the feature is within the caliper's specified measuring capacity.
Is the Mitutoyo 505-745 a digital caliper?
No. The 505-745 is an analog mechanical dial caliper. It does not require batteries and provides readings through its mechanical dial.
