(a) Appointment.--The mayors of cities of the second and third class, and the several boards of county commissioners, may, respectively, appoint one or more persons to serve as sealers of weights and measures in the respective county or city. In cities of the first class, the sealers shall be appointed by the county commissioners of the county in which the said city may be located.

Any sealer appointed pursuant to an agreement for such combination shall, subject to the terms of his appointment, have the same authority and duties as if he had been appointed by each of the authorities who are parties to the agreement.

(b) Powers and duties.--The sealer of a city or of a county and his deputy sealers, when acting under his instructions and at his direction, shall, but only to the extent delegated by the department pursuant to section 4121 (relating to powers and duties of director and inspector) and memorialized in a memorandum of understanding executed pursuant to section 4125 (relating to division of responsibilities), have the same powers and shall perform the same duties within the city or the county for which appointed as are granted to and imposed upon the director by sections 4112 (relating to general testing and inspections), 4116 (relating to investigations), 4117 (relating to inspection of packages), 4118 (relating to stop-use, stop-removal and removal orders), 4119 (relating to disposition of correct and incorrect apparatus), 4120 (relating to police powers; right of entry and stoppage) and 4192 (relating to temporary or permanent injunctions).
