Description
- 1. Determination of oxygen content in the environment, cabins, tunnels, chemicals, and gases of industrial and mining enterprises to prevent suffocation accidents of maintenance personnel in an oxygen-deficient environment.
- 2. Detect the oxygen content in the exhaust gas of internal combustion engine and the oxygen content in the flue gas to achieve reasonable control of combustion and save fuel.
- 3. Determination of oxygen content in the storage of grains, vegetables, dried fruits, etc.
- 4. Analysis of oxygen content in breathing/anaesthesia machines, hyperbaric oxygen chambers, aerospace and diving operations in medical undertakings.
- 5. It is an indispensable experimental equipment for experiments in physics, chemistry, biology, etc. in middle schools, colleges, and medical schools.
