One common question that arises is whether thermometers are permitted on flights. This comprehensive guide will delve into the specifics, ensuring you have a hassle-free travel experience.

TSA Regulations on Thermometers

The Transportation Security Administration (TSA) is responsible for enforcing security measures at airports in the United States. According to their regulations, thermometers are generally allowed in both carry-on and checked baggage.

Liquid Thermometers

Liquid thermometers, such as those containing mercury or alcohol, are permitted in carry-on baggage in quantities less than 3.4 ounces (100 milliliters). They must be placed in a clear, quart-sized bag along with other liquids.

Digital Thermometers

Digital thermometers are also allowed in carry-on baggage. They do not need to be placed in a liquids bag.

Non-Contact Thermometers

Non-contact thermometers, such as infrared thermometers, are permitted in both carry-on and checked baggage.

International Regulations

It’s important to note that international regulations may vary. Always check with the airline or consult the official website of the destination country for specific guidelines.

To avoid any potential issues, consider the following tips when traveling with thermometers:

• Pack liquid thermometers in a secure, leak-proof container.
