Syscal Multi-TX

Syscal Multi-TX

The multi-Tx device is issued from the latest developments of IRIS Instruments. This resistivity and induced polarization measurement device features three 250W transmitters and 6 reception channels to reduce the acquisition time. This 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)
