The temperature range that it can measure falls between -37 degree Celsius (low freezing point) and 356 degree Celsius (high boiling point). Strip thermometers are inexpensive and quick to use. If your baby uses a pacifier, this may be an easy way for you to record their approximate temperature. Clean the thermometer according to the manufacturers directions before storing or reusing. A temperature over 100.4F (38C) most often means you have a fever caused by an infection or illness. In 1593, Galileo Galilei invented a rudimentary water thermoscope, which allowed temperature variations to be measured for the first time. If the liquid was only in the capilallary then the volume wouldn't make any difference to the sensitivity. As alcohol has a low boiling point, it wets the wall of alcohol thermometer of its place; on the other hand, the mercury does not wet the walls of the mercury thermometer glass.

A thermometer has two important components: (1) a temperature sensor (e.g., the pyrometric sensor in an infrared thermometer or the bulb of a mercury-in-glass thermometer) that fluctuates when the temperature changes, and (2) a mechanism of . It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb. What is the Average Surface Temperature of Saturn? mercury thermometers remain in common use in a variety of laboratory and testing uses. A Laboratory Thermometer is a tool using which one can measure the temperature and to be particular, this thermometer is used to measure temperatures much higher and lower than the human body temperature. "Out of the box" accuracy for such devices is generally about one scale division. The planet also has the lowest axial tilt of any planet in the Solar System approximately 0.027 compared to Jupiters 3.1, (the second smallest). Range is the converse of sensitivity, i.e., the longer the range, the lower is its sensitivity. Rectal readings may be uncomfortable to get for infants and small children. Place the thermometers tip underneath the tongue. In order to get an accurate reading from oral use, the tip of the device must be placed under the tongue with the mouth completely closed.
