China Multi-Channel Portable Electrochemical Corrosion Meter

CST800E multi-channel portable electrochemical corrosion Meter integrates the electrochemical impedance spectroscopy (EIS).Portability, easy operation, fast measurements and results' direct display features it. EIS method is employed to measure the solution resistance (Rs), the polarization resistance (Rp) and further to obtain the accurate corrosion rate. It is especially suitable for corrosion environment where the Rs value is high(eg. waste water containing oil, soil, or concrete).
CST800E can achieve auto timing measurements with the built-in timer. It can be powered by both AC and DC(built-in rechargeable batteries). Battery power supply at full stage can support continuous measurements for 60hours.
CST800E can not only be controlled manually by keyboard, but also be controlled remotely for auto timing measurements. A 16M bytes flash memory to store up to 500,000 groups of data. Data can be saved even after the power is off in the wild. The measured data can also be sent to the PC with the USB cable. Under the control of EisTools software, it is convenient to analyze, save the data, and display the polarization resistance, solution resistance, and corrosion rate vs. time curve on the PC screen. The software can also help the user to forecast the development of corrosion based on corrosion rate.
The instrument could not only be controlled by panel keyboard, but also be controlled by EisTools software via serial communication port. Therefore, remote control and data read is achievable.

Applications

1. in-situ corrosion rate measurements and corrosion inhibitor evaluation and screening in petroleum& chemical industry, building &bridge construction site.
2. metal corrosion rate measurements in high-resistance system such as wastewater containing oil, soil, concrete.

Software Introduction
EisTools software can be used to download and analyze corrosion data stored in CST800E corrosion meter. It has a good compatibility with windows XP/win7/win8/win10. The main functions include: data files management, graphical display of polarization resistance, solution resistance, open circuit potential and corrosion rate curves. All graphics can be cut and pasted into Word document. It can output data file with ASCII format for further data processing.
EisTools software can fully control CST800E device, set up parameters and start the measurement. By USB interface, the user can use a laptop or a desktop to control.
