👉 Viatometers are devices used to measure temperature, pressure, humidity, and other physical properties of an object. They consist of a tube or container with openings for air and water. The opening of the tube is closed at one end, and the other end is open to the environment. A liquid in the tube then flows into the open end, causing it to rise above its surroundings. This pressure difference causes a temperature change, which can be measured by the presence or absence of this rise.
