The multi-Tx device is one of the most recent instruments developed by RIS Instruments. This resistivity and induced polarization measurement device features three 250W transmitters and six receiving channels to reduce the acquisition time. The underlying technology is based on the CDMA coding of the injected currents, enabling to compute the contribution of each transmitter on the total voltage received on each channel. In other words, in one injection, the multi-Tx is able to perform 18 resistivity and chargeability measurements with accuracy comparable to the Syscal Pro/R1.
This device particularly suits:
- The monitoring of rapid hydrological processes (when acquisition time must be reduced at constant measurement accuracy)
- All type of applications with an objective of increase of productivity (water resources, environment, civil engineering)
