Digital Inner and Outer Radius Measuring Instrument with 10mm/20mm/30mm/60mm/100mm Replaceable Measuring Claws 0-12.7mm

Advanced Design for Accurate Readings: The combination of mechanical, electronic, computer, and sensor technologies allows for precise measurement of any circular arc 's actual radius, enhancing reliability and efficiency. High Precision Technology: Featuring capacitive gate sensors and integrated circuits, this radius measuring instrument offers high accuracy with a radius measurement error of ΔR less than equal 0.01*R and a linear measurement error of ΔS less than equal 0.02mm. User-Friendly Operation: To achieve accurate measurements, gently position the measuring head on the object's , adjust the rod for close adherence, and read the displayed radius or diameter values directly from the digital display. Versatile Measurement Options: Equipped with five sets of interchangeable measuring claws (10mm/20mm/30mm/60mm/100mm), this tool adapts to various arc surfaces, ensuring precise radius measurements for diverse applications. Maintenance and Usage Tips: Keep the measuring head clean to prevent measurement discrepancies caused by oil or dust. tight contact during measurement and verify the stability of the display reading to avoid errors from vibrations or interference.
