Sec. 3. The board of commissioners of every county of thirty thousand (30,000) population or more shall, and the board of commissioners of any county of less than thirty thousand (30,000) population may appoint a county inspector of weights and measures.  No person shall be appointed as a county inspector of weights and measures in any county unless such person shall have been approved by the division of weights and measures of the Indiana department of health, and no county inspector of weights and measures in any county shall be removed by the board of commissioners without the approval and consent of the division of weights and measures.  The compensation of a county inspector of weights and measures shall be determined by the board and paid out of the county treasury.  It shall not be obligatory upon the board of county commissioners of such counties containing a city or cities which are already provided with an inspector of weights and measures or city sealers to make such appointments.  The board shall provide the necessary apparatus and supplies for the said inspector of weights and measures and the county councils of such counties shall appropriate such sums of money as are necessary for the salary and maintenance of the office.  Two (2) or more adjoining counties, by appropriate action of the boards of commissioners of such counties, may form an inspection district and provide by mutual agreement for the appointment of a district inspector of weights and measures.  The compensation of such inspector shall be apportioned among the counties forming the district in proportion to the population thereof.
