Abstract

A component concentration measurement apparatus measures a concentration of a measurement target component in a chemical solution and includes a metal housing and a resin housing accommodated in the metal housing, in which an electrical device that drives an analysis device that analyzes the chemical solution is installed in the metal housing, and a pipe through which the chemical solution flows and the analysis device are installed in the resin housing.

First claim

What is claimed is:

1 . A component concentration measurement apparatus that measures a concentration of a measurement target component in a chemical solution, the component concentration measurement apparatus comprising:
a metal housing; and a resin housing accommodated in the metal housing, wherein an electrical device that drives an analysis device is installed in the metal housing, the analysis device analyzing the chemical solution, and a pipe through which the chemical solution flows and the analysis device are installed in the resin housing.

2 . The component concentration measurement apparatus according to claim 1 , wherein the electrical device is provided inside the metal housing and outside the resin housing.

3 . The component concentration measurement apparatus according to claim 1 , wherein
the metal housing and the resin housing each include an opening and closing door, and the opening and closing door of the resin housing is provided with a translucent region.

4 . The component concentration measurement apparatus according to claim 3 , wherein the opening and closing door of the resin housing includes a translucent resin material.

5 . The component concentration measurement apparatus according to claim 1 , wherein
a protrusion protruding toward an outward surface of the opening and closing door of the resin housing is provided on an inward surface of the opening and closing door of the metal housing, and when the opening and closing door of the metal housing is closed, the opening and closing door of the resin housing is pressed in a closing direction by the protrusion.

6 . The component concentration measurement apparatus according to claim 5 , further comprising a holding mechanism that holds the opening and closing door of the resin housing in a closed state.

7 . The component concentration measurement apparatus according to claim 3 , wherein the resin housing includes a plurality of the opening and closing doors.

8 . The component concentration measurement apparatus according to claim 1 , wherein
a fixing bracket is attached to an outer surface of the resin housing, and the resin housing is fixed to the metal housing via the fixing bracket.

9 . The component concentration measurement apparatus according to claim 8 , wherein
the metal housing and the resin housing each include an opening and closing door, the opening and closing door of the resin housing is provided with a translucent region, and the opening and closing door of the resin housing is attached to the fixing bracket.

10 . The component concentration measurement apparatus according to claim 1 , wherein
a support bracket provided with a tap hole is attached to an outer surface of the resin housing, a through hole is formed at a position corresponding to the tap hole on a side wall of the resin housing, and the analysis device installed in the resin housing is screwed and supported in the tap hole of the support bracket.

11 . The component concentration measurement apparatus according to claim 1 , wherein
an inclined surface is formed on a bottom surface of the resin housing, and a drain port is formed in a lower region of the inclined surface.

12 . The component concentration measurement apparatus according to claim 11 , wherein
the inclined surface is formed all over the bottom surface, the inclined surface is provided with an attachment portion having an upper surface on which a horizontal attachment surface is formed, and a control valve that controls a flow rate of the chemical solution is attached to the horizontal attachment surface.
