Digital caliper Tesa 00530323 — 300 mm measuring range, IP67 protection

Tesa digital caliper model 00530323 offers precise linear measurement up to 300 mm with a clear digital readout. Designed for external, internal and depth measurements, the caliper combines a stainless contact system with robust sealing to meet IP67 protection. The device is suitable for workshop metrology, production quality control and engineering applications where reliable, repeatable results and resistance to dust and water are required.

Advantages

The caliper provides fast digital readout for accurate measurements without manual interpolation errors. IP67-rated sealing protects the slider electronics from dust and temporary immersion in water, improving durability in harsh shop-floor environments. Its construction ensures stable jaw alignment and minimal play for repeatable external and internal measurements, while the depth rod allows straightforward depth checks. The instrument's user-friendly display and simple button controls reduce setup time and measurement errors.

Suitable for

• Workshop metrology and routine part inspection
• Quality control in production lines
• Mechanical engineering and design verification
• Field measurements in dusty or wet environments

Key specifications

• Measuring range: 0–300 mm
• Measurement functions: external, internal and depth
• Protection class: IP67 (dust-tight and temporary immersion resistant)
• Display: digital LCD readout for direct value reading
• Material highlights: corrosion-resistant contact surfaces and sealed electronics

How to use

Before measuring, clean contact surfaces to remove chips or debris. Zero the display with the jaws closed, then position the caliper jaws on the part for external measurements, or use the inner jaws for bore measurements. For depth measurements, extend the depth rod until it contacts the bottom of the feature and read the value from the display. Apply consistent, light measuring force and keep the sliding beam parallel to the measurement axis to avoid measurement errors.

Usage recommendations

Store the caliper in a protective case when not in use, avoid prolonged exposure to aggressive chemicals, and rinse the sealed parts with clean water if contaminated; after immersion or washing, dry and verify zero before measuring. For traceable quality control, periodically check accuracy against gauge blocks or a calibrated standard.
