What is the use of maxium and minium thermometer?

Maximum and minimum thermometers are used to measure and record the highest and lowest temperatures over a specific period. The maximum thermometer typically contains Mercury or alcohol that expands and rises in a glass tube, marking the highest temperature reached. Conversely, the minimum thermometer uses a different mechanism, often a bulb with a liquid that contracts and leaves a mark at the lowest temperature. These thermometers are particularly useful in meteorology and climate studies for tracking temperature fluctuations.
