Digital ABS AOS Caliper

Mitutoyo 500-178-30 – Digital ABS AOS digital caliper 0–150 mm / 0–6″

The Mitutoyo 500-178-30 is an accurate and robust digital ABS AOS digital caliper that provides reliable measurement results for a wide range of applications in machine shops, production, and quality control. It utilises Mitutoyo's ABSOLUTE measurement system and AOS inductive sensor, which together ensure reliable and trouble-free measurement even in dirty or challenging environments.

Key features

- Measuring range: 0–150 mm / 0–6″
- Resolution: 0.01 mm / 0.0005″ – clear and informative display.
- Accuracy: ± 0.02 mm / ± 0.001″ – repeatable and reliable.
- ABSOLUTE measurement: no need to reset after switching on the power – the caliper automatically detects the correct initial zero point.
- AOS inductive sensor: operation is not disturbed by dirty scales or the environment – for example, oil, dust, or low humidity will not degrade the signal.
- ZERO/ABS function: you can set zero at any point for reference measurements and return to the ABS display as required.
- SPC data output: allows you to transfer measurement results directly to quality control or measurement systems (cable/adapters to be ordered separately).
- Depth measuring rod: a round depth measuring rod (Ø 1.9 mm) is included for deeper measurements.
- LCD display: clear display with large digits for easy reading.
- Ergonomics: finger wheel adjustment ensures smooth and comfortable control of the sliding part.
- Long battery life: under normal use, the battery lasts for several years without replacement.

Why choose Mitutoyo ABS AOS Caliper

The Mitutoyo 500-178-30 is designed to reliably and quickly measure all common dimensions – OD, ID, depth, and pitch – with a single tool. The ABSOLUTE measuring system eliminates the need to reset the measurement after power off, making work faster and reducing the likelihood of errors. The AOS inductive sensor ensures stable measurement results even when the scale is exposed to contaminants or the stresses of the working environment.

The measuring heads on this model are generally steel-type standard jaws (not in a special carbide-coated form), making the instrument versatile for basic measurements without the requirement for special jaws.
