An atmospheric corrosion measurement system of reluctance probe is established to realize quick measurement of metal corrosion in different simulated atmospheric conditions.

With a view to the corrosion of the reinforcing steel bars in reinforced concrete,foil-grating resistance probe samples and a device for monitoring of the corrosion of the reinforced concrete were designed and prepared so as to realize online monitoring of the corrosion of the reinforcing steel bars in the reinforced concrete.

The development and application of the resistance probe and testing instrument for high-temperature corrosion monitoring were introduced.

In addition to the positioned thickness measurement, the electro-chemical measurement, resistance probe and inductance probe techniques were also the effective methods in corrosion monitoring.

This paper studies and analyses the key factors which induce fluctuation of corrosion data measured by electrical resistance probe based on principle of temperature compensation,and it was found that the main factos are contact potential between different metals and differential temperature potential due to the temperature drift.

Based on the principle of electrical resistance probe corrosion monitoring,this paper develops ER400 electrical resistance probe corrosion monitoring equipment applied in gas field environment,and the resistance resolution is 0.

The fundamentals and structure of an electromagnetic probe for measurement of HPM is described in this paper.
