A novel device used in the wire beam electrode (WBE) method was developed in our lab. The system consists of standard modules, and is controlled by a LabVIEW software (National Instruments Co., NI). Since all the components in this WBE test device are commercially available, and the detailed information of the modules can be readily accessed by researchers, the system is easy to be built and modified, depending on experimental designs. The device can perform desired measurements, which is controlled by programs written in LabVIEW, for which the researchers can easily design and modify to create user-defined tests and control applications. This device has a faster measurement rate than that in published literature. In our study, we have used this device for the first time to investigate the relationship between local potential/current patterns and H(2)O(2) distribution in an artificial biofilm/stainless steel interface. The results showed that the electrochemical distribution of the biofilm-related system is closely correlated with the biofilm heterogeneity. The device improves the WBE measurement techniques and is expected to be widely used in academic and industrial fields.
