Digital Caliper Mahr RT MAHR 150 mm IP67, no data output

The Digital Caliper Mahr RT MAHR 150 mm IP67 is a compact precision measuring tool designed for accurate inside, outside and depth measurements up to 150 mm. The caliper features a digital display for clear, direct readout and a durable housing with IP67 protection against dust and temporary water immersion. The model does not include a data output interface, offering a straightforward handheld instrument for workshop and inspection tasks where robust environmental protection is required.

Advantages

The caliper combines a 150 mm measuring range with an IP67 rating, providing reliable performance in dusty or wet environments. Its digital readout simplifies measurement reading and reduces parallax error compared with analog scales. The construction emphasizes durability and ease of use, with a compact form factor suitable for handheld operation. Absence of a data output keeps the instrument simple and maintenance-light for routine dimensional checks.

Suitable for

• Workshop measurements of machined parts
• Quality control and dimensional inspection on the shop floor
• Field measurements where dust or temporary moisture is present
• Inside, outside and depth measurement tasks on small to medium components

Key specifications

• Measuring range: 0–150 mm
• Measurement functions: outside, inside and depth
• Protection class: IP67 (dust-tight and protected against temporary immersion)
• Display: digital readout for direct measurement reading
• Construction: compact handheld caliper with durable housing
• Data interface: no data output included

How to use

Before measuring, ensure the jaws and measuring surfaces are clean and the caliper is powered on. Zero the display with the jaws closed if required. For outside measurements, place the object between the main jaws and slide until contact is firm but not forceful; read the value on the digital display. For inside measurements, use the smaller jaws at the top of the caliper and expand until they contact the internal surfaces. For depth measurements, extend the depth rod until it contacts the bottom of the feature and read the measurement. Handle the instrument carefully and avoid applying excessive side loads or impacts.

Usage recommendations

Store the caliper in a protective case when not in use, avoid prolonged exposure to corrosive liquids, and periodically clean and calibrate the instrument to maintain measurement accuracy. Replace batteries promptly to prevent leakage and verify zero before critical measurements.
