Inside Outside Caliper

Product Code : SCL-PLE-11641

Inside and outside calipers are fundamental mechanical metrology instruments used to measure internal diameters, bores, and external dimensions of three-dimensional objects. Primarily utilized in secondary vocational workshops and tertiary engineering laboratories, these tools teach students the principles of indirect measurement and precision transfer. They are essential for curricula focusing on mechanical engineering, machining, and technical drafting for vocational students.

Technical Specifications

Educational Benefits & Features

Feature: Ergonomic curved leg geometry.

Benefit: Enables students to access internal cavities and span convex external surfaces where a linear rule cannot physically reach, solving the problem of measuring irregular mechanical components.

Feature: High-carbon steel architecture.

Benefit: Prevents flexing during measurement application, ensuring students achieve repeatable and high-fidelity data during metrology exercises.

Feature: Adjustable friction joint or spring nut.

Benefit: Maintains the specific measured dimension securely while the student transfers the tool to a secondary scale, reducing human error during the data transcription process.

Feature: Precision-ground hardened tips.

Benefit: Resists wear and blunting from repeated contact with abrasive metallic workpieces, ensuring long-term instrument accuracy in high-traffic vocational settings.

Feature: Polished aesthetic finish.

Benefit: Reduces the accumulation of industrial contaminants and skin oils, simplifying the sterilization and maintenance protocols required in shared educational environments.

Curriculum Alignment
