PROBLEM TO BE SOLVED: To provide a washer which can monitor secure rinsing of an object to be washed.SOLUTION: A washer is provided with a first electric conductivity sensor 48 which measures electric conductivity of drainage from a washing tank 2 or circulation water in the washing tank 2, and preferably is further provided with a second electric conductivity sensor 49 which measures electric conductivity of water supply to the washing tank 2. A washing process of washing the object to be washed by using a washing liquid, a drain process from an inside of the washing tank 2, and a rinsing process of rinsing the object to be washed by using rinsing water are sequentially conducted. In the rinsing process, the electric conductivity by the first electric conductivity sensor 48 is monitored. Preferably, in the rinsing process, rinsing is carried out until a difference between the electric conductivity by the first electric conductivity sensor 48 and the electric conductivity by the second electric conductivity sensor 49 becomes a set value or lower.SELECTED DRAWING: Figure 1 |
