Product Overview
The Mitutoyo 505-743J dial caliper measures outside, inside, depth and step dimensions across a 0"–8" (0–203.2 mm) range. It provides a clear analogue reading with 0.001" graduation and ±0.002" accuracy, without batteries or an electronic display.
The caliper is made from hardened stainless steel and features an ultra-smooth sliding mechanism with shock protection. Titanium coating on the sliding surfaces supports durability, while the bright yellow dial uses large characters for easy reading. The silver cover and 185 g weight make it suitable for routine workshop measurement.
The 505-743J is suited to machine shops, QC inspection, maintenance teams, power and desalination plants, and oil and gas service contractors 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 203.2 mm, a 10 °C temperature difference corresponds to roughly 23.4 μm of dimensional change.

Frequently Asked Questions
What range does the Mitutoyo 505-743J dial caliper measure?
It measures 0"–8" (0–203.2 mm).
Can it measure inside and depth dimensions?
Yes. It measures outside, inside, depth and step dimensions.
Why choose a dial caliper over a digital one?
The dial caliper 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 special about the 505-743J sliding mechanism?
The model features ultra-smooth sliding, shock protection and titanium coating on the sliding surfaces to support durable daily operation.
What is the cover colour?
The 505-743J has a silver cover and a bright yellow dial with large characters for readability.
Which model should I choose if my part is outside 0"–8"?
The 505-743J covers 0"–8". Other 505 series models can be selected when a different measuring range is required, including the 505-746 for a 0"–12" range.
Can the Mitutoyo 505-743J 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, protect the instrument from direct sunlight and coolant, avoid dropping it, and check the zero regularly. Periodic calibration is recommended when measurement traceability is required.
