Why are digital thermometers used these days?

Digital thermometers have replaced mercury thermometers because mercury is toxic. [Personal commentary: digital thermometers are not accurate and mercury thermometers are so how many people are being harmed by not knowing their temperature versus how many would be harmed by the mercury if accurate thermometers were still used?]


Why do OSHA and EPA and the AMA all discourage the use of mercury filled clinical thermometers?

When mercury filled thermometers break, the mercury is released. Mercury is toxic to people, pets and the environment. There is a long history of mercury from broken thermometers and other medical devices being improperly dealt with, or even ignored. Since there are adequate replacements for mercury thermometers, OSHA, EPA, AMA and others discourage the use of mercury thermometers and encourage their replacement with thermometers using other technologies.


Why do you flick thermometers before using them?

This is only in the case of of clinical thermometers, which usually have mercury inside them. These thermometers have a constriction just after the bulbthat allows the mercury to flow due to the pressure of expansion and contraction but is thin enough not to allow the mercury back into the bulb, to allow people to read the thermometer without having to hurry. people flick the thermometers to force the mercury back into the bulb so that temperature can be taken again.


Why can't you use mercury thermometers?

Mercury is toxic and poses serious health and environmental risks if the thermometer were to break. Safer alternatives, such as digital thermometers or alcohol-filled thermometers, are now commonly used instead.


Why is mercury no longer used in thermometer?

Mercury, if it enters your body, causes severe brain problems, and is usually deadly, so it is a poisonous material. it is no longer used in thermometers because thermometers were breaking and too many people were dying.


What people think about the use of mercury?

You would have to ask around about what people think, but mercury (Hg, atomic #80) is a transition metal, and one of only two elements which are liquids at room temperature and standard pressure. It is toxic to humans by contact with skin, which absorbs it quickly. Its most common everyday use is in thermometers.


What is Mercury used in?

Mercury was commonly used in thermometers and barometers. However, because it is poisonous, people are trying to use it in less things now.

How did people measure the temperature in 1960?

They had thermometers that were a glass tube with mercury sealed inside. There were temperature markings on the outside of the tube that when the mercury reached that point it showed what the temperature was.


What does the metal Mercury do?

Mercury vapors are toxic for people but it's widely used in everyday life (thermometers) and in science too. Also people use it in chemistry because it's very well understood.


What is the best thermometer to use on people?

An aural (in ear) thermometer is a good modern device, and measures the temperature in the outer ear. It is more expensive than a mercury clinical thermometer, but is simpler to prepare between patients, and completely avoids the problems of broken glass thermometers, and spilt mercury. Mercury clinical thermometers are however quite cheap.


Why is mercury used in clinical thermometers?

These days, mercury is considered too risky to use in thermometers (due to the risk of them breaking and contaminating people). Alternate techniques are used today in clinical thermometer, including electronic thermometers and ones based on liquid crystals that aren't as harmful should they leak out and even contactless infrared thermometers..Mercury was used in clinical thermometers due to:Its high thermal expansion (25 °C) 60.4  µm·m−1·K−1Linearity in thermal expansionSensitivity to rise in temperature
