Product Overview
The Mitutoyo 505-742J dial caliper measures outside, inside, depth and step dimensions across a 0"–6" (0–152.4 mm) range. Its clear analogue dial provides a 0.001" graduation and ±0.001" accuracy without batteries or an electronic display.
The caliper is built from hardened stainless steel and features an ultra-smooth sliding mechanism with strong shock protection. Titanium coating on the sliding surfaces supports durability, while the bright yellow dial uses large characters for easy reading. The model has a silver cover and weighs 175 g.
The 505-742J is suitable for oil and gas maintenance workshops, refinery and petrochemical shutdown crews, CNC machine shops, QC inspection and general industrial measurement in Kuwait.
For close-tolerance measurements, allow the caliper and workpiece to reach the same temperature before measuring. Steel expands approximately 11.5 μm per metre per °C; over 152.4 mm, a 10 °C temperature difference can result in approximately 17.5 μm of dimensional change.

Frequently Asked Questions
What range does the Mitutoyo 505-742J dial caliper measure?
It measures 0"–6" (0–152.4 mm).
Can it measure inside and depth dimensions?
Yes. The 505-742J measures outside, inside, depth and step dimensions.
Why choose a dial caliper over a digital one?
The dial design requires no batteries and has no electronic display, providing a conventional analogue measurement method.
How do I read the dial?
Read the whole-unit measurement from the beam scale, then add the dial reading. The graduation is 0.001" per division.
What is the cover colour?
The 505-742J has a silver cover and a bright yellow dial with large characters for readability.
What are the key construction features of the 505-742J?
It uses hardened stainless steel construction, an ultra-smooth sliding mechanism, shock protection and titanium-coated sliding surfaces.
Which model should I choose if my part is outside 0"–6"?
The 505-742J covers 0"–6". The Mitutoyo 505-742 is another 0"–6" option, while the 505-744 also covers 0"–6" with OD carbide-tipped jaws.
Can the Mitutoyo 505-742J 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 it?
Wipe the measuring faces clean after use, keep the instrument away from direct sunlight and coolant, avoid dropping it, and check the zero regularly. Periodic calibration is recommended when measurement traceability is required.
