Three types of thermometers are alcohol, liquid crystal, and infrared radiation (pyrometer). The three main temperature scales are Celsius, Fahrenheit, and Kelvin. Temperatures can be converted from one scale to another using temperature conversion equations.
Usually, the function of the kink in the thermometer is to break the flowing connection of mercury in the capillary and the bulb area at the lower end of thermometer. In laboratory thermometer, the temperature is measured continuously to note temperature change. … Therefore, a laboratory thermometer does not have a kink.
A clinical Thermometer is meant for clinical purposes. It is developed for measuring the human body temperature. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature.
Those days have passed. Since 2001, 20 states have banned mercury “fever thermometers” for medical use, and regulations tighten every year. … But as of today the federal government has more or less killed the mercury thermometer in the United States—NIST has announced it will no longer calibrate mercury thermometers.
The best thermometers you can buy
No-touch or non-contact infrared thermometers measure temperature through the forehead from a close distance in seconds. They may be used on newborns and older people. They’re easy to use and may reduce the risk of spreading disease by allowing more physical distancing.
Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).
There are different types, but not all thermometers are right for your child.
For example, there is one set of thermometers that are used to measure body temperature while another set of thermometers to measure boiling point and freezing point during experiments. Here, we will discuss the two types of thermometers, namely, clinical thermometer and laboratory thermometer.
A thermometer is used to measure how hot or cold something is. There is a number scale showing temperature going from cold at the bottom to hot higher up.
iCelsius is an amazing thermometer app for android and iOS users that allows you to easily get the temperature on your smartphone. You don’t need to buy any extra thermometer to measure body temperature. It is a popular digital thermometer by which you can easily get fever temperature.
Best thermometer overall: iProven Forehead and Ear Thermometer DMT-489. Best thermometer on a budget: Vicks Comfort Flex Thermometer. Best infrared non-contact thermometer: iHealth No-Touch Forehead Thermometer PT3. Best thermometer for daily testing: Kinsa Quick Care Smart Thermometer.
The different types of medical thermometers
1. Digital thermometers provide faster results. Digital thermometers provide fast results as opposed to mercury thermometers whose readings are slower to realize because you have to wait for the mercury to heat and then slowly rise to display the temperature.
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
A laboratory thermometer has a long stem with a silver bulb at the end. The silver color in the bulb usually means there is mercury in it. Mercury becomes bigger as the temperature becomes hotter. But mercury is a poison to humans.
