Electronic thermometers are acceptable, but mercury thermometers are not.
Different types of thermometers have different requirements for carrying them on an airplane. The mercury thermometer cannot be taken with you, it can only be registered, and the mercury thermometer must be placed in a protective box.
If you want to travel by plane with a thermometer, it is recommended that you bring an electronic thermometer. However, please note that if the electronic thermometer contains a lithium battery, the energy rating of the lithium battery does. does not exceed 100 Wh or the lithium content does not exceed 2 grams. Please take precautions as long as short circuit measures are taken, it is acceptable to carry it on the plane.
Not allowed on the plane:
1. Prohibited food products:
Milk, pickles, fruitfresh sea s, etc. Fresh food, tropical fruits with a particularly strong aroma, such as jackfruit, durian, and gelatinous foods like fermented tofu, honey, shrimp paste, and hot sauce cannot be taken on board the plane . If necessary, they can be recorded.
2. Items prohibited for transportation of handicrafts:
Exquisite shell handicrafts, fruit knives, as well as sharp and blunt instruments such as axes and hammers may become obstacles to travel. You should choose consignment.
3. Items prohibited from carrying cosmetics:
Items to note include: lotion, mascara, face cream, hairspray, nail polish, lip gloss, hair gel, shampoo and perfume. , deodorant gel, toothpaste, hand cream, hand sanitizer, mouthwash,etc. You can carry liquid cosmetics, gels and sprays of less than 100 ml on the plane.
Can a mercury thermometer pass safety inspection?
It's not a big problem if you use it for a short time, but it is recommended to replace the battery as soon as possible.
The black plastic is the rubber shell of the battery. It wraps around the core of the battery. In addition to being beautiful and suitable for use with terminal machines, it can prevent dust and impurities from entering the battery. core to prevent the battery core from being punctured, etc. Without its protection, as soon as something pierces the exposed part of the battery core, it can leak or explode.
In addition, if certain metal elements such as iron enter the inner layer of the battery, the battery may also explode.
Thus, for long-term considerationsIn the long term, it is recommended to replace it with another one. This can be used as a backup battery for occasional use.
How do I know the battery model of the watch?
Yes. Only one mercury thermometer is permitted for personal use and must be placed in a protective box. Transporting an electronic thermometer. If the electronic thermometer contains a lithium battery, the rated energy of the lithium battery should not exceed 100 Wh or the lithium content should not exceed 2 grams.
The thermometer can pass the security check. Only one mercury thermometer is permitted for personal use and must be placed in a protective box. Transporting an electronic thermometer. If the electronic thermometer contains a lithium battery, the rated energy of the lithium battery should not exceed 100 Wh or the lithium content should not exceed 2 grams.
The mountain pile modelre is determined by looking at the bottom cover of the movement. The back of the movement is the technical heart of the watch. Many watch manufacturers engrave the watch model at a prominent location on the bottom of the movement.
Common typical models are: 6F22 (9V), 4F22 (6V), 15F20 (22.5V), 10A (9V), 11A (6V), 23A (12V), 25A ( 9V), 26A (6V), 27A (12), 476A (6V), 120H7D (8.4V), 2X625A (3V) and more.
Detailed information:
The battery life of the watch varies from one to ten years. To avoid a sudden power outage, quartz watches will usually notify you 1-10 days in advance.
There are five types of watch batteries, namely lithium batteries, silver oxide batteries, silver peroxide batteries, solar cells and lithium batteries. mercury oxide. Each of these five types of batteries has its own advantages and disadvantages. You have to choose based onof the type of watch when replacing them.
1. Lithium battery: using lithium metal as the negative electrode, it has the characteristics of high voltage (generally 3V), low self-discharge rate and long storage time.
2. Silver Oxide Battery: Voltage is 1.55V. It is the most commonly used battery in quartz watches. It has high energy density and stability and has no environmental pollution.
3. Silver peroxide battery: Also known as divalent silver battery, voltage 1.55V. It has high capacity but poor voltage stability.
4. Solar Cells: Can convert light energy into electrical energy.
5. Mercury oxide battery: The voltage is 1.35V. This is the first watch battery developed. Due to environmental pollution, it is rarely used.
