METR 111 - Physical Metrology

3 Credits: (2 lecture, 3 lab)

Course Description
This course is a study of physical metrology emphasizing the theory and proper use of applied mechanical measurement equipment. The intent is to develop the student’s interest and understanding of physical metrology along with a thorough knowledge of laboratory technique.

Note Field trips may be required. Spring semester only.

Prerequisite PHYS 101 or permission of instructor. Corequisite METR 110 or permission of instructor.
