Liquid-in-glass ThermoMeter

The liquid thermometer utilizes the principle of thermal expansion and contraction of liquids to reflect temperature changes through variations in the length of the liquid column in a sealed glass tube. Common liquids used include mercury or alcohol, and it is employed for environmental monitoring in laboratories, warehouse management, and temperature and humidity recording in industrial settings.
Selection
When selecting, pay attention to the range matching the usage scenario. Industrial applications require shock-resistant structures, while laboratory settings opt for models with finer scale divisions. Consider the characteristics of the medium: mercury has a wide temperature measurement range, while alcohol is suitable for low-temperature environments. Choose the shell material—stainless steel or plastic—based on the corrosive nature of the environment.
