What is laboratory thermometer ? What is simple thermometer?

The thermometer which is used to measure temperature of substances in lab is cqalled laboratory thermometer. 

Laboratory thermometers are devices used to measure temperature. ... While a lab thermometer can measure how hot or cold a sample or environment is, the range of measurement can vary widely between models.A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances.

Clinical thermometers are used to measure the body temperature of humans. Whereas laboratory thermometer is used to measure the temperature of objects. CLINICAL THERMOMETER Use to measure human temperature .Place the end of the thermometer with the reservoir of liquid in the testing medium. For example, if you are testing the temperature of ice water, place the reservoir in the water, below the ice, but not touching the bottom of the flask or cup the water is held in. This will garner a more accurate temperature.

It is used to measure the temperatures in school or other laboratories for scientific purpose as they measure temperatures to a range higher than clinical thermometers. One such thermometer is known as the laboratory thermometer with a scale generally ranging from –10°C to 110°C.For example the clinical thermometer will only measure between 80 and 106 degrees because that is the range of body temperatures for humans. A laboratory themometer will cover a much larger range, including boiling point and absolute zero.

The clinical thermometer is used to measure body temperature, however, laboratory thermometer is not used for the purpose of measuring body temperature. The temperature range of clinical thermometers is 35°C to 42°C and that of laboratory thermometers is -10°C to 110°C.
