Description features:The new Anyi High Precision Digital Caliper provides an extra high resolution of 0.005mm for higher precision use. The clear LCD makes it easy to read. All High Precision Digital Calipers also include an output port for RS equipped devices. This type of digital caliper is a tool for the most experienced toolmakers and machinists when the higher resolution is needed. High Precision Digital Caliper, whose resolution is 0.005mm or 0.00019 inch, is finer than those regular ones, whose resolution is only 0.01mm or 0.005inch, in the aspect of accuracy. Especially when Micrometering is applied, its measuring accuracy will turn out much higher. Its permissible error, which is nearly half of that of regular ones within the same measuring range, makes the measuring more accurate. Major features: 1. Zero-setting. 2. Data Output. 3. Resolution: 0. 005mm. 4. Lock to hold the slide in position. 5. Depth rod for depth measurement. 6. Hardened stainless steel measuring surface for long life. 7. Long life battery 8. Precision exceeds DIN862-88 9. Inch/mm conversion 10. Manual on/off.
