Mercury Thermometers For Precise Lab Measurement

Mercury thermometers are traditional liquid-in-glass temperature measuring instruments that use mercury as the thermometric fluid. As temperature changes, the mercury expands or contracts, moving along a calibrated scale to indicate the temperature. Known for their accuracy, stability, and wide measurement range, mercury thermometers are commonly used in laboratories, industrial processes, and educational settings, though their use has declined due to mercury’s toxicity and environmental concerns.
