R.I. Gen. Laws § 47-3-1
No person engaged in the trade of buying and selling shall have or permit to be kept at his or her place of business or upon any cart, wagon, or other vehicle used by him or her in carrying on his or her business, any weight, measures, or balance, of whatever description, which is not at the time duly sealed in accordance with chapters 1 and 2 of this title, or which, having been sealed, is no longer correct. If the weights, measures, or balances can be readily adjusted by such means as the sealer has at hand, the sealer may adjust and seal them; but if they cannot be readily adjusted, the sealer shall either seize the weights, measures, and balances forthwith and destroy them, or shall affix to them a notice forbidding their use until the sealer is satisfied that they have been so adjusted to conform to the standards; and whoever removes the notice without the consent of the officer affixing the notice, shall for each offense be fined not less than one hundred dollars ($100) nor more than two hundred dollars ($200), one-half (½) to the town or city and one-half (½) to the use of the complainant.
