UNSPSC 41111500: Weight measuring instruments

UNSPSC 41111500 Weight measuring instruments is a Class code covering maintenance, repair, and procurement of scales and measurement systems used in transportation, water infrastructure, and laboratory operations. State and local governments buy under this code for preventative maintenance and calibration of weigh station scales, water meter installation and replacement services, and laboratory measurement equipment including digestion blocks and related analytical systems. The issuing bodies include state transportation departments, municipal water utilities, city purchasing divisions, and county health departments. Work scopes range from certified technician maintenance of Weigh-in-Motion and static scale systems at distributed locations to vendor-supplied equipment with installation and training.
