Patent ID: 11739006

Abstract:
A water quality measurement device 1 includes a twin tube excimer lamp 2. The inflow pipe 3 is connected to one end of the inner tube 21 of the excimer lamp 2, and the outflow pipe 4 is connected to the other end of the inner tube 21 of the excimer lamp 2. The detector 5 that measures the conductivity of sample water is interposed in the outflow pipe 4. In the water quality measurement device 1, sample water sequentially flows through the inflow pipe 3, the inner tube 21 of the excimer lamp 2, and the outflow pipe 4. Hence, the channel in the water quality measurement device 1 can be simplified. Additionally, the sample water is oxidized by being irradiated with UV light in the inner tube 21 of the excimer lamp 2. Hence, it is possible to irradiate the sample water with UV light from the excimer lamp 2 efficiently.
