Brand-new design: Modern appearance and updated construction that reflect current technology and performance expectations, improving usability and handling without changing core measuring functions. Precise measurement: Measures from 0 to 100 mm with a resolution of 0.01 mm (0.00039 in) for consistently detailed, repeatable readings when small differences matter. Ratchet handle for consistent force: Built-in ratchet mechanism ensures the same measuring force on each reading, reducing user-caused variation and improving measurement reliability in repeated checks. Durable, long-term performance: Robust construction designed for regular workshop or inspection use and to maintain stable performance over time. Key benefits — why you need this tool Reliable precision: The 0–100 mm range combined with 0.01 mm resolution lets you verify small tolerances and catch fit or finish issues before they become problems. Repeatable results: The ratchet handle removes guesswork about applied pressure, producing uniform measurements across multiple users and sessions. Built for daily use: A sturdy build reduces the need for frequent replacement or repair, lowering downtime and cost of ownership. What it does and how it fits into your workflow Function: Precision measuring instrument for dimensional checks across a standard 0–100 mm span. Performance: High-resolution readings (0.01 mm / 0.00039 in) suitable for workshop inspection, production quality control, and precision assembly. Compatibility: Suited for general manufacturing, maintenance, and laboratory environments where standard metric measurements are required. Typical use scenarios Production quality control: Quickly verify part dimensions on the line to ensure components meet specified tolerances and prevent out-of-spec assemblies. Machine shop inspections: Measure finished parts, shim thicknesses, or assemblies during setup and final inspection to confirm machining accuracy. Maintenance and assembly: Check mating surfaces and component fits in automotive, aerospace, or equipment repair to ensure reliable reassembly.
