"Laboratory thermometer is used to measure the temperature of all things, except the human body."
Why can't it be used for humans?
A laboratory thermometer is used to measure the temperature during various experiments. It can measure a wide range of temperature, typically from -10 0C to 110 0C. But this thermometer is not so sensitive to measure human body temperature.
A clinical thermometer measures temperature that lies between 32 0C and 42 0C.
