Claims

[Scope of Claim for Utility Model Registration] 1. A narrow hollow cylinder with a closed bottom, with a heating heater in contact with the side surface and connected to a heating power source through a terminal.The upper opening of the hollow cylinder is funnel-shaped. An expandable, removable lid is provided so that it can be fitted into the upper opening, a small hole is inserted in any part of the lid, and a rod-shaped temperature sensor and a pair of parallel metal electrodes are placed in the center of the lid. Protruding in the direction of the cylinder center axis,
The pair of parallel metal electrodes is set longer than the rod-shaped temperature sensor, and the rod-shaped temperature sensor is immersed in the brake fluid, and the tips of the pair of parallel metal electrodes are slightly connected to the brake fluid liquid level. An indicating thermometer with an indicating position fixing device is connected to the rod-shaped temperature measuring sensor, which is set apart from the space so that it is perpendicular to the brake fluid level, and the indicating position fixing device is connected to the power supply. Brake fluid boiling point temperature measuring device connected to a pair of parallel metal electrodes. 2. A thin hollow cylinder is made into a U-shape, the openings at both ends are spread out in a funnel shape, and removable lids are provided so that they can be fitted into both openings, and a small hole is passed through any part of one or both of the lids, Claim 1 of the Utility Model Registered Claim: A rod-shaped temperature sensor is mounted on the lid, and a pair of parallel metal electrodes are set to be shorter than the length of the rod-shaped temperature sensor and protrude from the other lid. Brake fluid boiling point temperature measuring device.
