Levelnic is a digital level.
It’s very useful to measure the flatness, levelness and straightness of working machine.
It’s a tool that can be used easily and conveniently by anyone.
Although tools like laser interferometer, autocollimator and bubble level are capable of measuring the same thing but it needs more time, more costs and needs to be used by an expert and not everyone can perform the same measurement easily.
Only the Levelnic can be used by beginners easily.
