A British company has made a gas analyzer for packaging foods. It can measure and analyze the carbon dioxide and oxygen content of packaged foods with an accuracy of 98%, and can be widely used for gas monitoring of fish foods and prepackaged fruit and vegetable packaging products. When used, analytical data can be printed out, including gas analysis results, product codes, serial numbers, date and time, and more.
It is also called a choking collar, which is recommended by almost all dog trainers. Its principle is that as soon as the dog leash is pulled, the collar will be temporarily tightened, which will make the dog`s neck feel oppressive, and at the same time this collar will make a jingle that dogs don`t like. This is an effective way to correct the dog's wrong behavior.
