Document Type and Number:
Japanese Patent JP7373426
Kind Code:
B2
Abstract:
A water quality measurement device (100) includes a flow channel (130), an ion sensor having a responsive film portion whose surface is disposed in the flow channel (130), a glass-electrode-type sensor having a glass electrode whose surface is disposed in the flow channel (130), a drive section (115), a first opening-closing section, and a second opening-closing section. When a storage condition is satisfied, the water quality measurement device (100) puts the first opening-closing section in a first closed state and puts the second opening-closing section in a second closed state, thereby producing a state in which the surface of the responsive film portion and the surface of the glass electrode are present in a common closed space (135) whereby the closed space (135) is put in a wet state without the surface of the responsive film portion being immersed in the liquid.
