The Induced Polarization Transmitters
TxII-5000W-2400V with 10,000W- 4800V option available
TxII-3600W-2400V with 7200W- 4800V option available
TxII-1800W-2400V

At last, three high-quality affordable
IP Transmitters.

New: Link two GDD 3600W or 5000W IP Tx together and increase the power and voltage:

from 3600W-2400V to 7200W-4800V;
from 5000W-2400V to 10,000W-4800V;
or even mix a 3600W-2400V with a 5000W-2400V to make a 8600W-4800V.

For Induced polarization surveys, use the new 8 to 32 channels receiver with the proven 1800W/3600W/5000W-2400V transmitters.

For Pulse EM, use the GDD IP transmitter to increase current by 400% in a 4km loop. Recently in Saskatchewan, Canada , 8A were sent in a surface loop of 16km diameter.

Up and down: The TxII-5000W-2400V transmitter in operation

New TxII-5000 watts - 2400 volts Model
10,000W- 4800V option available

Its high power, up to 10 amperes, combined with a standard 220/240V generator makes it particularly suitable for pole-dipole Induced Polarization surveys. This transmitter allows to transmit up to 20 times more current for pole-pole survey where one needs high voltage to transmit higher current in a very resistive ground to be able to take readings at the receiver. As reported by GaiaScan Geophysics Ltd.: «Fast current set saves us about 25% of survey time and that is a very substantial saving.»

• This 5000 watts induced polarization (I.P.) transmitter works from a standard 220/240V generator source and is well adapted to rocky environments where a high output voltage of up to 2400 V is needed. Moreover, in highly conductive overburden, at 350 V, the highly efficient TxII-5000 watts transmitter is able to send a current of up to 10 amperes. By using this I.P. transmitter, you obtain fast and high-quality I.P. readings even in the most difficult conditions.
