The AMT/FSL-TDGJ multi-channel steel corrosion monitoring device is a real-time online monitoring equipment for the corrosion of reinforced concrete. It adopts a pre embedded concrete monitoring composite probe, which can monitor parameters such as concrete resistivity, Cl - concentration, pH value, half cell potential, and steel corrosion rate in real time. It is designed according to the national standard "GBT 43667-2024 Technical Specification for Corrosion Monitoring and Detection of Reinforced Concrete". Widely used for online monitoring of corrosion rate of reinforced concrete in buildings, highways, bridges, and tunnel structures. MT/FSL-TDGJ has become a powerful tool for monitoring steel corrosion and concrete chemical environmental parameters in industrial sites, predicting the durability, safety, and service life of reinforced concrete structures.The AMT/FSL-TDGJ multi-channel steel corrosion monitoring instrument is powered by AC through a DC12V power adapter. The measurement parameters and automatic measurement intervals of the instrument can be configured through a PC, and the measurement results are automatically saved in non-volatile memory for data analysis and plotting processing. Alternatively, the CST610 wireless data transceiver can be used to transmit data to the cloud and display it through web access.
