DIGI MET® 300 mm workshop caliper — digital inductive system with measuring tips and fine adjustment (Mahr / Helios‑Preisser)

The DIGI MET® 300 mm workshop caliper is a robust digital measuring instrument for precise external, internal and depth checks in workshop and production environments, designed for repeatable results under everyday workshop conditions

• Digital inductive measuring system, moisture-resistant
• High reading resolution 0.01 mm
• Includes measuring tips and fine adjustment
• Variable data output: USB, RS232, Digimatic

Consistent accuracy where it matters most

The caliper delivers a reading resolution of 0.01 mm over a 300 mm measuring range, combining a non‑contact inductive measuring system with mechanical robustness. The inductive system reduces wear and provides stable readings even when surfaces are slightly contaminated, while the moisture‑resistant design counters the effects of hand sweat and workshop humidity. As a result, measurement drift is minimised and production decisions can be made with greater confidence — an essential benefit for repeat operations and quality checks.

Easier, faster measuring with fine control

Equipped with measuring tips and a fine adjustment mechanism plus a locking screw, the caliper enables controlled approach and secure clamping of the jaws for reproducible measurements. The 90 mm jaw length improves access to deeper features, and the QuickLock function allows single‑point zeroing and key lock to prevent accidental changes. The PRESET function speeds repetitive tasks by loading a reference value, so setups and short‑run inspections are faster and less error‑prone.

Seamless data capture and process integration

Data export is supported via USB, RS232 and Digimatic, enabling direct connection to SPC systems or data loggers for traceable records. The LCD display (character height 8.5 mm for the 300 mm version) presents readings clearly on the shop floor, and the instrument is marked as subject to inspection, ensuring it fits into documented calibration and quality regimes. QuickStart electronics and zero setting at any point facilitate immediate use and straightforward integration into existing measurement processes.

FAQ

What is the smallest increment the caliper can display?
The instrument shows measurements in 0.01 mm increments; the DIGI MET® 300 mm workshop caliper provides that resolution throughout its 300 mm range.

Can the caliper be used in damp workshop conditions?
Yes — the digital inductive measuring system and moisture‑resistant construction mean the caliper is designed to withstand hand sweat and everyday workshop humidity without loss of accuracy.

Which data outputs are available for logging measurements?
Data export is possible via USB, RS232 and Digimatic, so readings from the DIGI MET® model can be routed directly to SPC systems or data collectors.

Is the instrument suitable for internal as well as external measurements?
The caliper includes a dedicated internal measurement approach; for the 300 mm range the internal measurement reach is specified as 10 mm.

Does the caliper require calibration or inspection?
The product is marked as subject to inspection; regular calibration and documentation are recommended to meet quality management requirements for workshop and production use.
