【Abstract】 According to the principles of corrosion electrochemistry, an atmosphere corrosion monitoring system has been designed with microprocessor to monitor the corrosion rate, temperature, relative humidity and pH value for underground engineering. Its measuring unit is highly sensitive, it can automatically select suitable scale and continuously measures the data. In communication with each slave, its master can control each slave to measure in cycle or at random, and it can also receive, store, process and display the data from the units. It can transfer the measured data to personal computer for further processing and receive PC’s control. The system is useful to monitor the atmosphere corrosion environment in underground engineering.更多还原
