There are a variety of cost-effective, mercury-free alternatives available at local pharmacies. These alternatives include digital, glass gallium-tin, and glass alcohol thermometers. Because of the health risks associated with mercury exposure from broken thermometer, it is very difficult any more to find glass mercury thermometers.
Alcohol or digital sensors are commonly used as alternatives to Mercury in thermometers. Alcohol thermometers use a colored liquid inside a glass tube that expands with temperature changes, while digital thermometers use electronic sensors to measure temperature.
A liquid used in termometers should probably have the caracterstics such as having a high melting point, opaque, uniform expanding rate etc. One such liquid is alcohol. It has a melting point of 110 degree celsius. Such thermometers are usually found in laboratories.
Some thermometers (the red or blue "weather" type thermometers) have used colored alcohol for years. There's been a bit of a push to eliminate mercury from the more precise lab thermometers, though, and it's now possible to buy thermometers that use a gallium alloy ("galinstan") that melts at around 254 K. These are a bit more difficult to produce than mercury thermometers, though, since gallium wets glass... an undesirable property in a thermometer.
Hardly any options in contrast to mercury have now been created. One of which incorporates galinstan that is a fluid compound of gallium , indium and tin. Liquor Thermometers. Alcohol thermometers are supplanting mercury thermometers in numerous applications. They utilize liquor as the filled in fluid in glass tubes.
Typically, thermometers with a red liquid are filled with an alcohol that contains a dye. These are called "spirit-filled".
Because of the toxicity of mercury, most thermometers these days are manufactured using alcohol that's been colored (usually red) to make it easier to see.

They used to.
But it's quite poisonous and bad for the Environment, so it's been replaced by less dangerous substances.

What do they use instead of mercury thermometer?
Digital thermometers, infrared thermometers, and alcohol or galinstan thermometers are commonly used as alternatives to mercury thermometers due to the environmental and health risks associated with mercury.
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.
What is the name of the liquid in which thermometer is dipped?
The liquid in which a thermometer is typically dipped is called mercury. Mercury is commonly used in old-style thermometers, but newer thermometers may use alcohol or other liquids instead.
What type of liquid do you use in a thermometer?
Typically, thermometers use either mercury or alcohol as the liquid inside the glass tube to measure temperature. Mercury thermometers are being phased out due to the toxicity of mercury, with alcohol thermometers being a safer alternative.
Why is Mercury used in thermometers instead of alcohol?
Mercury has a higher coefficient of expansion compared to alcohol, which leads to a more precise measurement of temperature. Mercury is also less affected by changes in atmospheric pressure and does not evaporate easily, making it a more reliable substance for use in thermometers.
What you can use instead of mercury?
Instead of mercury, you can use alternative materials like digital thermometers instead of mercury thermometers for temperature measurement. In addition, you can opt for alternatives such as lead-free solder in electronics and non-mercury batteries for environmental-friendly options.
Is there mercury in thermometers today?
Most modern thermometers no longer use mercury due to its toxicity. Instead, digital thermometers, infrared thermometers, and other types of thermometer technology that do not contain mercury are widely available and recommended for safer use.
What do they use instead of mercury thermometer?
Digital thermometers, infrared thermometers, and alcohol or galinstan thermometers are commonly used as alternatives to mercury thermometers due to the environmental and health risks associated with mercury.
How are mercury thermometers used today?
Mercury thermometers are still used in some industrial applications and laboratories due to their accuracy and ability to measure high temperatures. However, their use is declining due to the potential health and environmental risks associated with mercury exposure. In many situations, digital thermometers or other types of non-mercury thermometers are used instead.
Why is mercury not used in thermometers any more?
Mercury is toxic and poses serious health and environmental risks if spilled. As a result, many countries have phased out the use of mercury in consumer products, including thermometers. Safer alternatives, such as digital thermometers, are now widely used instead of mercury-based ones.
What is used in thermometers now instead of mercury?
Many modern thermometers use a colored alcohol solution, typically dyed red or blue, instead of mercury. These alcohol solutions have lower toxicity levels than mercury and are safer to use in household and medical applications. Other alternatives include digital thermometers that use thermistors or infrared technology to measure temperature.
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.
What is in a thermometer besides Mercury?
Some thermometers use alcohol or dyed alcohols like ethanol instead of mercury. These liquids expand and contract with temperature changes, allowing the thermometer to measure the temperature. Digital thermometers use electronic sensors to measure temperature.
What was used in thermometers in 1600 instead of mercury?
Before the use of mercury, alcohol (usually ethanol or dyed spirits) was commonly used in thermometers. Alcohol thermometers were popular because alcohol has a lower freezing point than mercury, making them suitable for a wider range of temperatures.
Why don't thermometers use Mercury?
Mercury is Toxic.
What is a non mercury thermometers?
A non-mercury thermometer is a thermometer that does not contain mercury as the temperature-sensing liquid. Instead, it may use alcohol, galinstan, or other materials to measure temperature. These alternatives are considered safer for environmental and health reasons compared to mercury thermometers.
A use for the element mercury?
