Whether or not you can bring a thermometer into an airport depends on the type of thermometer and the airport's specific policies. Some airports may prohibit thermometers with defined points, while others may allow certain types of thermometers, such as probe thermometers. Digital thermometers and those with red lines instead of silver are typically allowed. The final decision rests with the TSA officer, who may consider factors such as the presence of batteries, the type of liquid in the thermometer, and whether it triggers security concerns during screening.

What You'll Learn
Thermometers with mercury are allowed in checked baggage
It is recommended to declare the item to the airline and follow any specific instructions provided by the carrier. Some airlines may have additional requirements or restrictions, so it is always best to check with the airline before travelling.
When packing a mercury thermometer in checked baggage, it is crucial to take precautions to prevent breakage. Wrap the thermometer in protective material, such as bubble wrap or clothing, and place it in a sturdy case or box. Ensure that the case or box is labelled clearly as fragile to handle it with care.
Additionally, it is essential to be aware of any local regulations or restrictions regarding the disposal of mercury. In some jurisdictions, there may be specific guidelines for the proper disposal of mercury-containing items. It is the responsibility of the traveller to ensure that they are compliant with all relevant regulations.
While thermometers with mercury are generally allowed in checked baggage, it is always advisable to check with the specific airline and airport regulations before travelling. Rules and restrictions can vary, and it is essential to ensure compliance with all applicable guidelines to ensure a smooth travel experience.

Digital thermometers are allowed in carry-on baggage
In addition, while digital thermometers are generally allowed, there may be variations in airport regulations. Some airports may have stricter rules, and it is ultimately at the discretion of the TSA officer whether an item is allowed through the checkpoint. It is always recommended to check with the specific airport and airline for their latest guidelines.
It is worth noting that some sources suggest that thermometers, in general, are not allowed by the TSA. This may be due to concerns about the potential presence of mercury, which is a restricted substance. However, digital thermometers do not contain mercury and are therefore not subject to the same restrictions.
To ensure a smooth screening process, it is advisable to properly pack and declare your digital thermometer. You may inform the airline that you are carrying a digital thermometer, and they may provide specific instructions or guidelines. Additionally, keep in mind that even if an item is generally permitted, it may be subject to additional screening or prohibited if it triggers security concerns.

Thermometers with a red line are non-mercury and not restricted
When it comes to travelling with a thermometer, it's important to be aware of any restrictions, especially regarding mercury thermometers. Mercury thermometers are commonly used for household fever thermometers, as well as oven, candy, and meat thermometers. However, due to the potential release of harmful mercury vapours if the thermometer breaks, some states and municipalities have passed laws restricting their manufacture, sale, and distribution.
If you're planning to bring a thermometer to the airport, it's crucial to know that thermometers with a red line instead of silver are non-mercury and not restricted. These thermometers are safe to carry and do not pose the same risks as mercury thermometers. Digital thermometers are also typically allowed, unless they are powered by lithium batteries, which may be subject to certain restrictions.
Non-mercury thermometers have made significant improvements in recent years. They offer comparable accuracy and temperature ranges to mercury thermometers. For example, non-mercury thermometers with temperature ranges up to 260° C can have accuracy limits of ± 1°-2° C, which is similar to mercury thermometers in the same range. Additionally, non-mercury thermometers are non-toxic and environmentally friendly, providing a safer alternative.
When travelling with a thermometer, it's always a good idea to check the latest guidelines provided by the relevant authorities, such as the Transportation Security Administration (TSA) or local airport regulations. These guidelines may vary depending on your location and the specific type of thermometer you're carrying. Keeping yourself informed ensures a smooth travel experience and helps you adhere to any necessary safety precautions.

TSA officers have discretion over items at checkpoints
Thermometers are allowed in airports, but there are some restrictions. TSA officers have the discretion to decide whether an item is allowed through the checkpoint. Even if an item is generally permitted, it may be subject to additional screening or not allowed through if it triggers an alarm, appears to have been tampered with, or poses security concerns.
Digital thermometers are allowed in carry-on baggage. One small medical or clinical mercury thermometer for personal use is also allowed when carried in a protective case in checked baggage. The individual must advise the airline of the presence of the mercury barometer or thermometer in the carry-on baggage. However, some airlines, like Cathay Pacific, do not allow mercury thermometers.
Probe thermometers are allowed, but some people have had issues with TSA officers at specific airports confiscating them because they have a defined point at the end, which is not permitted. It is worth noting that this may be an exception made by the specific airport or the individual officer, as thermometers are generally allowed per TSA Standard Operating Procedures (SOP).
TSA officers may also ask you to power up your electronic devices, including cell phones, at the checkpoint. Devices that cannot be powered on will not be permitted onboard the aircraft.

Batteries in thermometers may be an issue
The rules regarding bringing a thermometer on a plane vary depending on the type of thermometer and the airport. It is important to note that the final decision rests with the TSA officer at the checkpoint. If a thermometer is allowed, batteries may still be an issue. Some airports do not allow any lithium batteries, while others only prohibit large rechargeable lithium batteries. It is best to check with the specific airline and airport before travelling.
Digital thermometers are typically allowed and are not restricted. However, it is worth noting that some digital thermometers may contain rechargeable lithium batteries, which could be prohibited. If the thermometer has a removable battery, it may be worth taking it out and packing it separately. This will ensure that the battery does not turn on during transit and cause a security concern.
Some sources suggest that probe thermometers are allowed, while others indicate that any item with a defined point is prohibited. Again, this may vary depending on the airport and the officer's discretion. If in doubt, it may be best to pack the thermometer in checked baggage to avoid any issues.
Additionally, some thermometers contain mercury, which is a restricted substance. However, small medical or clinical mercury thermometers for personal use are allowed in checked baggage if they are in a protective case. It is important to advise the airline of any mercury-containing devices in carry-on baggage.
