Abstract

A water quality measurement deviceincludes a twin tube excimer lamp. The inflow pipeis connected to one end of the inner tubeof the excimer lamp, and the outflow pipeis connected to the other end of the inner tubeof the excimer lamp. The detectorthat measures the conductivity of sample water is interposed in the outflow pipe. In the water quality measurement device, sample water sequentially flows through the inflow pipe, the inner tubeof the excimer lamp, and the outflow pipe. Hence, the channel in the water quality measurement devicecan be simplified. Additionally, the sample water is oxidized by being irradiated with UV light in the inner tubeof the excimer lamp. Hence, it is possible to irradiate the sample water with UV light from the excimer lampefficiently.
