Digital ABS AOS Caliper, ID/OD Carb. Ja.

Mitutoyo 500-234-30 – Digital ABS AOS Caliper, Carbide-coated jaws 0–150 mm
The Mitutoyo 500-234-30 is a high-quality digital ABS AOS caliper that combines the ABSOLUTE measurement system and AOS (Advanced Onsite Sensor) inductive sensor – this technology ensures reliable, repeatable, and accurate measurement results even when the scale is exposed to oil, dust, or other contaminants. The gauge features carbide-coated inner (ID) and outer (OD) jaws that are resistant to wear and particularly suitable for hard or difficult-to-measure surfaces in applications such as machining and industrial production.
Key technical data
- Measuring range: 0–150 mm – a general and versatile range for measuring external and internal points.
- Resolution: 0.01 mm – clear and accurate display value.
- Accuracy: ± 0.02 mm – repeatable and robust over the whole range.
- ABSOLUTE (ABS) measurement: does not require resetting after switching on the power – the original zero point is retained in memory.
- AOS inductive sensor: no signal loss even if the scale is contaminated by oil or dust.
- Carbide-coated jaws: both inner (ID) and outer (OD) jaws with carbide coating ensure long life and durability even in difficult measuring applications.
- LCD display: large and easy-to-read display for easy reading of results.
- Depth gauge: flat depth gauge included for basic measurements.
- Data output: possibility of data output (SPC/PC) with optional accessory, facilitating documentation and monitoring of measurement results.
- Battery life: very long – about 5 years under normal use.
- Ergonomics & glide: smooth and stable measurement motion enhances user comfort.
