Product features

Android phone APP, connected to the host through wifi, the field is easy to operate

Multidimensional data display, Discover and deal with all issues on-the-spot, instant positioning

Monitoring host instrument provides extremely rich software functionality, to assist clients in handling issues and adjusting settings under different field applications. This allows the data recording of various ambient data and survey procedures in a fashion as real, complete, objective as possible. Detailed functionalities are as follow:

  • It has alarms for the open circuit, the short circuit and the current voltage out-range, and problems can be found timely and solved instantly.
  • Main interface displays I, V, R0, η, M, the electrode locations of A, B, M and N. The bottom greyed interface shows the grayscale bar of V, I, R0, standard deviation at any specific survey locations. Total survey points, remaining survey points and estimated time remaining are also displayed during data acquisition.
