<p>Material: Alloy, ABS.</p><p>Range: 0-25mm x 0.001mm.</p><p>Head Measurement Diameter: 0.63 cm / 0.25 inch.</p><p>Mounting hole diameter: 1.2 cm / 0.47 in.</p><p>Measuring head length: 0.36 cm / 0.14 in.</p>1. The probe head of the digital micrometer adopts professionally designed diameter ratchet force measurement, which is more accurate for small power propulsion and has high measurement accuracy. 2. The LED head of the handheld digital micrometer has a measuring range of 0-25 (mm), clear reading, efficient and convenient operation. 3. The digital micrometer probe is made of alloy and ABS material, which makes it sturdy and wear-resistant, not easy to damage and can be used for a long time. 4. Metric and Imperial Units The electronic micrometer head supports the conversion of metric and imperial units and can acquire data as needed.It allows not only to measure absolute values, but also to add numerical values. 5. The digital micrometer head is made of sturdy and wear-resistant materials to ensure long-term use.It is small, easy to maintain, easy to design, simple to operate, ratchet diameter force measurement and small power feed measurement are more accurate. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
