Product Overview
The Mitutoyo 505-739 dial caliper measures outside, inside, depth and step dimensions across a 0"–8" (0–203.2 mm) range. Its easy-to-read analogue dial provides 0.001" graduation, while ID/OD carbide-tipped jaws are designed to resist wear during repeated measurement of abrasive and hardened materials.
The mechanical dial requires no batteries or electronic display, providing a straightforward reading for routine dimensional inspection. The caliper has a stated accuracy of ±0.002" and weighs approximately 185 g.
Standard outside and inside jaws, a depth bar and step measurement capability allow the 505-739 to handle a broad range of everyday inspection tasks. It is suitable for machinists, QC inspectors, maintenance teams, CNC machine shops, and oil and gas service operations across Kuwait.
Temperature can affect dimensional measurements. Steel expands by approximately 11.5 μm per metre for every 1 °C change. For a 203.2 mm workpiece, a 10 °C temperature difference can produce roughly 23.4 μm of dimensional change. Allow the workpiece and Mitutoyo 505-739 to reach the same temperature before taking a final precision reading.
For a different 0"–8" configuration, the Mitutoyo 505-743 is another option in the 505 series.

How to Use the Dial Caliper
-
Clean the measuring faces and close the jaws gently.
-
Check the dial zero before beginning the measurement.
-
Open the jaws beyond the feature being measured.
-
Position the appropriate jaws against the workpiece.

Read the whole-unit measurement from the main scale and the fractional measurement from the dial.
-
Use the depth bar for depth measurements and the step surfaces for step dimensions.
Frequently Asked Questions
What range does the Mitutoyo 505-739 measure?
It measures from 0"–8" (0–203.2 mm).
What are the graduation and accuracy?
The 505-739 has a 0.001" graduation and stated accuracy of ±0.002".
Can it measure inside and depth dimensions?
Yes. The caliper measures outside, inside, depth and step dimensions.
What are carbide-tipped jaws for?
The carbide tips on the measuring jaws are designed to resist wear from abrasive or hardened materials, helping maintain the condition of the measuring faces during repeated use.
Why choose a dial caliper instead of a digital caliper?
The 505-739 uses a mechanical analogue dial and does not require batteries or an electronic display. This can be useful in workshop environments where a mechanical measuring instrument is preferred.
Which Mitutoyo model should I choose if my required range differs?
Choose a caliper whose measuring range covers the required dimension. The 505-739 covers 0"–8"; other 505 series models can be selected according to jaw configuration, graduation and application requirements.
Can the Mitutoyo 505-739 be recalibrated?
Yes. Periodic calibration through an ISO/IEC 17025-accredited calibration service can help maintain measurement traceability.
How should I store and care for the caliper?
Wipe the measuring surfaces clean after use, protect the instrument from coolant and direct sunlight, avoid impacts or drops, and check the zero position regularly. Periodic calibration should be scheduled according to your quality requirements.
