High end version of snorkel breathing tube airflow resistance tester, diving breathing tube airflow resistance tester

1、 Core functions and detection principles

A diving breathing tube is a simple submersible that involves diving breathing apparatus for diving enthusiasts and belongs to the category of underwater operation equipment. It consists of three parts: gas supply float, respirator, and gas hose. During use, the air supply float floats on the water surface, and air enters through the umbrella shaped intake pipe and is transported to the respirator through the gas hose.

The use of breathing tubes in teaching is a familiar feeling for new students to breathe through their mouths. Used for snorkeling, the main equipment worn for snorkeling is goggles, breathing tubes, and fins, commonly known as the "Three Treasures of Diving". Diving enthusiasts engage in recreational and sightseeing diving in areas with high visibility and shallow water. The fun brought by snorkeling is no less than that brought by scuba diving.
