【Wide Measuring Range】 Covers 50–1000mm with optional configurations. One set meets most inner diameter measurement needs with 0.01mm precision—ideal for industrial-grade accuracy.
【Durable Alloy Probe】 Made of inlaid carbide for high wear resistance and long-term precision. Dark chrome plating resists corrosion and enhances measurement stability.
【Standard Calibration Tool】 Includes a 50mm standard caliper for quick self-calibration. Maintain accuracy easily before first use or after extended operation.
【Clear & Precise Scale】 High-strength rod with tight assembly. Laser-engraved scale (4-pass process) ensures clear, accurate readings that won't wear down over time.
【Protective Storage Case】 Comes in a shock-resistant sponge-lined plastic box. Easy to store, carry, and transport—perfect for fieldwork or workshop use.
