A New Oxygen Concentration Tester Design
Now, the industries such as chemical industry is develop rapidly, and the requirement for the chrome of O2 is higher and higher. In this situation, it is important to measure the oxygen density with a portable and exact measure device. This article makes some study on a device for measuring the oxygen density, focusing on the principle of the testing, and the hardware and the software of the device. It proved that the system can work well.
