Mercury s have been used for many decades in industries, laboratories, and households to . However, is a highly toxic substance that poses a severe health risk to human beings, wildlife, and the environment if not carefully handled or disposed of. Therefore, governments worldwide have banned the use of mercury thermometers, and people are encouraged to use alternative thermometers that are safer and environmentally friendly. In this article, we will discuss how to lower a thermometer without mercury.

The two most common types of thermometers that are safe and easy to use, apart from mercury thermometers, are digital thermometers and alcohol thermometers. Digital thermometers use electronic sensors to measure body temperature, while alcohol thermometers use a mixture of ethanol and colored liquid to indicate temperature changes. The following are simple steps on how to use each thermometer:

Digital Thermometer:

1. Turn on the thermometer by pressing the power button.
2. Insert the thermometer probe into the mouth, ear, or armpit, depending on the type of thermometer you have.
3. Wait for the thermometer to beep, indicating that it has taken an accurate temperature reading.
4. Remove the thermometer from the area and turn it off.

Most digital thermometers come with instructions that guide users on proper use, and they require no prior calibration or mercury disposal. Moreover, digital thermometers are portable, fast, and hygienic.

Alcohol Thermometer:

1. Hold the alcohol thermometer by its bulb end and flick your wrist to shake the thermometer and lower the temperature to a level below the desired reading.
2. Insert the thermometer into the area of measuring promptly.
3. Read the temperature once the colored alcohol line stops moving.
4. Keep the thermometer level while reading the temperature.
5. When finished, clean the thermometer with warm soapy water, and then rinse it with water before storing it.

Using an alcohol thermometer is simple and safe, but it requires calibration to maintain accuracy. Alcohol thermometers measure temperature changes by observing how the colored alcohol rises or falls in the thermometer, and if the liquid separates from the thermometer, the accuracy may be compromised.

In conclusion, mercury thermometers are no longer safe for use due to their toxic nature. Fortunately, digital and alcohol thermometers provide a safe and easy solution for measuring temperature without the dangers of mercury. Always read and follow the instruction manual that accompanies your thermometer to ensure proper use and accurate readings. To dispose of mercury thermometers safely, do not throw them in waste bins or flush them down the toilet. Instead, take them to authorized collection centers where they can be recycled or disposed of safely. Remember, everyone has a role to play in environmental protection, and switching to safer alternatives like digital and alcohol thermometers is one of them.
