Measurement Tools Portable by Amatrol introduces the fundamental principles of measurement including basic measurement, precision measurement, direct gauging, indirect gauging, and dimensional measurements using both the U.S. customary system as well as S.I. metric system. Understanding how to perform accurate measurements is relevant to technical careers such as quality control inspector, machinist, manufacturing engineer, operations manager, and production technician. The measurement training system’s compact size and durable case also provide for safe storage when available training space must be used to teach other topics.
