METR 110 - Dimensional Metrology

4 Credits: (3 lecture, 3 lab)

Course Description
This course is an introduction to metrology emphasizing the theory and proper use of dimensional equipment, collection and statistical treatment of data, and blueprint reading. The intent is to develop the student’s interest and understanding of metrology along with a thorough knowledge of laboratory technique. 

Note Field trips may be required. Spring semester only.
