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−1
- Linearity in thermal expansion
- Sensitivity to rise in temperature

Are digital and clinical thermometers same?
no,digital thermometers don't have mercury whereas clinical thermometers have mercury.
What liquid is inside thermometers?
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).

Why is mercury not used in thermometers any more?
Mercury is not used in thermometers, because mercury is poisonous.
What is the differences between a clinical thermometer and a laboratory thermometer?
Clinical thermometers are made to be used in a hospital to accurately determine body temperature. They are often digital. Lab thermometers are made of metal or glass and usually don't give you an accurate reading as much as a "ball park." A clinical thermometer may have mercury but lab thermometers usually have alcohol .
Which metal is used in clinical thermometer?
Mercury is used in clinical thermometers.
Are digital and clinical thermometers same?
no,digital thermometers don't have mercury whereas clinical thermometers have mercury.
Why is mercury used in clinical thermometer and not laboratory thermometer?
Mercury is no longer used much in thermometers due to the poisonous compounds that it forms. When I grew up, in Chemistry at school and at the doctors there were mercury thermometers and alcohol thermometers.
What chemical element is used in thermometers?
the element used in termometers is Mercury.
What liquid is inside thermometers?
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
What is the difference between clinical thermometers and other mercury-in-glass thermometers?
Clinical thermometers are specifically designed for measuring human body temperature, while other mercury-in-glass thermometers can be used for various purposes such as measuring temperature in laboratories or industrial settings. Clinical thermometers typically have a narrower temperature range focused on human body temperature, while other thermometers may have a wider temperature range. Additionally, clinical thermometers are often designed with features like an easy-to-read scale and a flexible tip for comfort and safety during use.

What liquid is found in a clinical thermometer?
The liquid in a clinical thermometer is often mercury. But there are thermometers that use a coloured alcohol.
What liquid mental is used for thermometers?
Mercury is used in thermometers.
Is Mercury used in thermometers?
In normal and some medical thermometers Mercury is used. That is why you may want to consider using electric thermometers which are more commonly used. They use no mercury.
What was Mercury used for?
mercury was used for thermometers and baramoters
