<p>PURPOSE:To automatically evaluate the deterioration degree of used oil by automatically measuring the change of the absorbancy of the used oil with respect to new oil by providing a hooking metal fitting capable of reciprocally moving a cell stand from a table to an absorbancy measuring part. CONSTITUTION:When a belt driving motor 23 is operated by the operation command from a control part, a timing belt 22 is moved. At this time, the hooking part 21a of a hooking metal fitting (engaging piece) is engaged with the groove 78 of a cell stand 5 and, in such a state that the cell stand 5 is hooked, for example, a cell 2 having new oil received therein is transferred from a table 8 to an absorbancy measuring part 10 and the absorbancy of the new oil is measured to return the cell 2 to the table 8. Subsequently, when the table 8 is rotated by a table driving motor 9, the hooking part 21a is separated from the groove 18 of the cell stand 5 to be engaged with the groove of the adjacent cell stand and, for example, a cell having used oil received therein is transferred to a measuring position to measure the absorbancy change of the used oil. By subjecting the absorbancy change of the used oil to the previously measured new oil to comparative operation, the deterioration degree of the used oil is evaluated.</p> |
