Digital float bath thermometer is a precision instrument used for measuring liquid temperature, particularly suitable for precise temperature control in chemical experiments. The probe can accurately measure the temperature inside the liquid, while the float ensures that the probe is stably suspended in the liquid, avoiding contact with the bottom or wall of the container, thereby obtaining more accurate temperature readings. In chemistry teaching, digital float bath thermometers can be used for heating, cooling, or maintaining specific temperature experiments such as dissolution, crystallization, distillation, etc. Its high precision and readability enable students to better understand and master the influence of temperature on chemical reaction rate and equilibrium, making it an important teaching tool in chemical experiments.
