As the vernier scale is manually operated, you won't need to use batteries. For extreme precision in your readings, it has an accuracy of 0.004 mm. Its micro-fine calibrations improve reading accuracy. You can lock the tool and take your values with ease thanks to the ratchet stop and spindle locking lever.
This instrument comes with all of the necessary adjustment tools in a convenient fitted case. You'll find precise hand-measuring tools like this one used in the aerospace industry, as well as in medical, clockmaking and laboratory applications.
