Abstract
PURPOSE:To detect degradation degree simply and surely, by measuring the reflection light quantity of a filter paper to which the lubricant is dropped. CONSTITUTION:Under the state where round filter paper 1 is put on the concave part of filter paper holder 2, the light which has the light quantity controlled by light source control part 3 is irradiated from light source part 4 to round filter paper 1, and the reflection light is received by photo detecting part 5, and the output of indicator part 6 at this time is read and is defined as the reference value. Next, after a fixed quantity of the degraded lubricant is dropped to round filter paper 1 and penetrates into all the surface, the light which has the light quantity controlled is irradiated again, and the output of indicator part 6 at this time is read. This output value is compared with the reference value. As a result, the output value for penetration of the lubricant is reduced according to degradation of the lubricant, and thus, the degradation degree of the lubricant is decided simply and surely.
