What Is a Maximum Thermometer?

The maximum thermometer is an instrument specially used to determine the maximum temperature in a certain interval (usually one day). ^[1]

The maximum thermometer is an instrument specially used to determine the maximum temperature in a certain interval (usually one day).

A glass needle is welded to the bottom of the mercury ball of the thermometer, and the tip of the needle is inserted into a capillary at the upper end of the eight mercury ball. There is also a glass needle, but a narrow area is created in the ball neck area. When the temperature rises, the top of the mercury column rises. When the temperature decreases, the mercury column is interrupted at the needle tip or narrow area and the mercury column above the needle tip or narrow area remains unchanged. Therefore, the indication at the top is the highest temperature since the last observation. ^[1]

The highest thermometer is an instrument used to determine the highest temperature in a certain interval (usually one day). The structure of the thermometer is basically the same as the ordinary thermometer, but a small glass tube is inserted in the neck of the mercury ball, or the mouth of the tube is tightened. When the temperature increases, the mercury expands and rises over the narrow neck, but when the temperature decreases, The mercury in the bulb shrinks. Due to the narrow neck, the mercury in the tube cannot fall into the bulb. The mercury column breaks at the neck and stays in the tube. Therefore, the temperature shown at the top of the mercury column appears within this interval. Maximum temperature. The maximum thermometer is placed on a wooden frame inside the louver, horizontally and horizontally, with the ball on the left and the top on the right. The maximum thermometer is placed obliquely when in use. ^[1]

Highest temperature meter, meteorological instrument to measure the highest temperature in a day. Temperature range: -16- + 81 division value: 0.5

Lowest temperature meter, meteorological instrument to measure the lowest temperature in a day. Temperature range: -52- + 41 division value: 0.5
