Substitute of mercury in clinical thermometer

Gallium indium tin thermometer will be used instead of mercury thermometer. As a safe, accurate and environmentally friendly green thermometer, gallium indium tin mixed metal thermometer is the best substitute for mercury thermometer. As a temperature sensing material, liquid metal of Ga-In alloy, like a mercury thermometer, reflects the body temperature of the tested person with its uniform physical characteristics of "shrinking when cold and expanding when hot".
