Simple answer: NAPT could not provide the services it does to the metrology community without it being nonprofit. Only because of the numerous sponsors, the donation of the kits, the volunteering of the technical advisors that assist in the design of the schemes and the one-on-one help given to members are we successful. All this could only happen in a nonprofit environment. In short, NAPT exists because of the metrology community supporting the services NAPT provides back to the metrology community.
