Precision Work Gauge Helios Preisser 1000 mm DIN 866/II plus6 (MPN 0452103)

Helios Preisser precision work gauge, 1000 mm length, manufactured to DIN 866/II plus6 standard. Designed as a reference straightedge and measurement standard for workshop and inspection tasks, it provides a calibrated datum for setting, checking and aligning machines, fixtures and tooling. The 1 m straightedge is intended for dimensional control, layout work and verification in production environments and metrology laboratories where a stable, certified straight reference is required.

Advantages

The gauge is produced to the DIN 866/II plus6 tolerance class, offering a reliably verified straightness and dimensional accuracy across its full length. Its construction minimises deformation and thermal distortion during normal workshop use, allowing repeatable alignment and inspection. The neutral, stable reference surface reduces measurement uncertainty when used with feeler gauges, indicators or optical checking devices. The straightedge combines a practical length for many machine set-ups with the precision required for calibration and quality control tasks.

Suitable for

• Setting and aligning machine beds, slides and fixtures
• Checking straightness and flatness over a 1000 mm span
• Layout and scribing work on metal and composite parts
• Reference standard for inspection benches and calibration routines
• Verification tasks in production and metrology laboratories

How to use

Position the precision work gauge on the surface or across the reference points to be checked, ensuring it rests evenly without lateral stress. Use appropriate supports or V-blocks if checking cylindrical parts or when elevating the gauge is required. Compare the reference surface against the test workpiece using feeler gauges, dial indicators or optical instruments; for alignment tasks, slide the gauge along the component while monitoring indicator readings. Handle the gauge with care to avoid impacts and store it in a protective sleeve or case when not in use to preserve calibration and surface condition.

Usage recommendations

Perform checks in a temperature-stable environment and allow the straightedge and workpieces to reach thermal equilibrium before measuring. Clean contact surfaces of chips, oil and debris prior to use. For traceable measurements, combine the straightedge with calibrated measuring instruments and follow established inspection procedures.
