Digital Caliper Mahr IP67 200 mm, model ET MAHR, no data output

Digital Caliper Mahr IP67 200 mm, model ET MAHR, is a handheld precision measuring tool designed for accurate linear measurement of external dimensions, internal diameters and depths within a 200 mm range. The instrument features an IP67-rated sealed construction that protects against dust ingress and temporary immersion in water, and provides a clear standalone digital readout without a data output interface. This model is intended for workshop, inspection and quality-control use where a robust, portable and easy-to-read caliper is required.

Advantages

The caliper combines precise sliding-measurement mechanics with a digital display for quick readings. IP67 sealing reduces the risk of damage from coolant, dust or accidental splashes, extending service life in demanding environments. Absence of a data output interface simplifies operation and reduces points of failure, while the 200 mm measuring range covers most workshop and inspection tasks. The tool’s compact form and intuitive controls support efficient handheld use.

Suitable for

• Quick external, internal and depth measurements on parts up to 200 mm
• Inspection and quality control in production and maintenance
• Workshops, tool rooms and on-site measurement tasks requiring sealed instruments

Key specifications

• Measuring range: 0–200 mm
• Protection rating: IP67 (dust-tight, temporary immersion resistant)
• Measurement functions: external, internal and depth
• Display: standalone digital readout (no data output interface)
• Form factor: handheld caliper with sliding beam

How to use

Before measurement, ensure the measuring surfaces are clean and the caliper is switched on and zeroed at the fully closed position. For external dimensions, close the jaws around the part and read the value from the digital display. For internal measurements, use the upper jaws and open them until they contact the inner faces. For depth measurements, extend the depth rod into the feature and read the result. Verify zero and recalibrate if necessary after temperature changes or mechanical shocks.

Usage recommendations

Store the caliper in a protective case when not in use, avoid prolonged exposure to aggressive chemicals, and replace the battery promptly when display brightness or stability decreases. Periodically check accuracy against gauge blocks or reference standards and keep measuring faces clean to maintain reliable measurements.
