ABSTRACT:
A water temperature gauge includes a first timer circuit in which a time for submerging the water temperature gauge to a position of a desired depth for measurement, and a measuring circuit for measuring the water temperature with the water temperature gauge after a lapse of the time set in the first timer circuit. A time which is obtained by adding a time required for the measuring circuit to measure the water temperature to the time set in the first timer circuit is set in a second timer circuit so that the measurement with the measuring circuit is automatically terminated after a lapse of the time set in the second timer circuit and the as-measured value is stored in a memory circuit and displayed on a liquid crystal display. A fisherman can confirm the underwater temperature of his fishing place by lifting up the water temperature gauge on the water surface and recognizing the display.
