pH meter

Description

FIG. 1 is a perspective view of a pH meter;

FIG. 2 is a front view of the pH meter;

FIG. 3 is a rear view of the pH meter;

FIG. 4 is a left side view of the pH meter;

FIG. 5 is a right side view of the pH meter;

FIG. 6 is a top view of the pH meter;

FIG. 7 is a bottom view of the pH meter; and,

FIG. 8 is a reference view showing a transparent part.

This article is directed to measure hydrogen ion index (pH value) of a sample solution by measuring an electromotive force generated on a sensing film of a reference electrode (pH electrode). Parts of the design desired to be claimed is a reference electrode and a comparison electrode disposed in a tray where a sample is dropped. In this article, the comparison electrode can be mounted and demounted freely, and thus the solution measured can be added to a container in the tray.

The solid line part indicates a part desired to be claimed. In FIG. 8 showing a transparent part, the shaded gray part is transparent. The broken lines are for illustrative purposes only and form no part of the claimed invention.

Claims

The ornamental design for the part of a pH meter, as shown and described.
