A Mercury Thermometer is a traditional, reliable device used to measure body temperature. It consists of a glass tube filled with mercury, which expands as the temperature rises, providing an accurate reading on the scale marked on the thermometer. The mercury thermometer is known for its high level of precision and has been used for decades in both medical and scientific settings.These thermometers typically have a clear glass body and can be used for oral, rectal, or underarm temperature measurements. The mercury column inside the tube rises or falls according to the body temperature, offering a clear, easy-to-read result. Although highly accurate, mercury thermometers are being phased out in many regions due to safety concerns related to the toxic properties of mercury.For best results, it is important to handle a mercury thermometer with care, avoid breaking it, and properly dispose of it if damaged.
