Digital Protractor INSIZE 2176-300 300 mm

The INSIZE Digital Protractor 2176-300 with a 300 mm measuring arm is an electronic angle measuring instrument designed for accurate determination of angles and slopes in workshops, metalworking and carpentry. Its digital readout provides quick numeric angle values while the compact construction and flat measuring surfaces allow contact on edges, faces and fixtures. Portable and battery-powered, this protractor is intended for on-site inspection, machine setup and layout tasks where repeatable angle measurement is required.

Advantages

The digital display delivers immediate angle readings with high resolution, reducing reading errors compared with analog gauges. The 300 mm arm offers a balance between reach and rigidity for stable placement on larger surfaces. Its compact, lightweight housing makes it convenient to carry and position in confined spaces; durable construction suits regular workshop use. Magnetic and flat contact surfaces enable firm seating on metallic parts and flat faces for consistent measurement.

Suitable for

• Checking and setting angles on machine tools and jigs
• Verifying slopes and inclinations on metal or wooden components
• On-site inspections and maintenance checks
• Layout and marking tasks in carpentry and sheet metal work
• Calibration and alignment of fixtures and assemblies

Key specifications

• Measuring arm length: 300 mm
• Display: digital numeric readout for angle values
• Measurement type: angle and slope determination
• Contact surfaces: flat mounting faces suitable for edges and planes
• Power: battery operated for portable use
• Construction: compact and lightweight housing for on-site tasks

How to use

Place the protractor so that its measuring arm and base make full contact with the surfaces or edge whose angle you intend to measure. Switch on the unit and allow the digital display to stabilise before reading. Read the numeric value directly from the screen; when measuring between two faces, ensure both contact surfaces are properly seated. For repeat measurements, reset or zero the instrument according to the manufacturer’s control functions and re-check placement to maintain consistency.

Usage recommendations

Handle the instrument on clean, dry surfaces and avoid striking the measuring edges. Replace batteries as needed and store the protractor in a protective case to preserve calibration. For highest accuracy, verify readings with a reference standard and perform measurements on stable, vibration-free workpieces.
