UltraEM Z4 magnetotelluric instrument is based on the mature magnetotelluric theory, the random signal processing technology, embedded real-time operating system technology, large-scale field programmable logic array technology, 32 A/D high precision and high speed recording technology and the latest electronic technology, electromagnetic high frequency earth (HMT), audiomagnetotelluric (AMT) and magnetotelluric (MT or LMT) as one of the wide band magnetotelluric instrument.


  • <strong style="color: inherit;"> Wide band magnetotelluric instrument,</strong> can use the high frequency magnetotelluric sounding (100kHz-10Hz) to carry out a few meters to a kilometer in the shallow depth of the human activity is the most active exploration, also can use audio frequency magnetotelluric sounding (10kHz-0.1Hz) or long period magnetotelluric (1kHz-1000s) to carry out deep research of macro geological problems.

  • <strong style="color: inherit;"> The natural source and artificial source mixed mode -- the</strong> application of magnetotelluric sounding principle, which can be carried out natural source magnetotelluric sounding, can also carry out artificial source electromagnetic sounding, or a mixture of the two acquisition.

  • <strong style="color: inherit;"> Tensor and scalar can be observed,</strong> can be carried out for fast screening of scalar measurement, can also carry out two or three dimensional geological structure tensor measurement.

  • <strong style="color: inherit;"> Efficient multi rate real-time parallel acquisition,</strong> 192kHz, 24kHz, 2400Hz, 150Hz, 15Hz five high speed sampling rate and parallel acquisition, the acquisition time is shorter, more efficient, complete 1000m (100kHz-5Hz) of the sounding point only 30 seconds, can effectively carry out the continuous EMAP observation; multirate sampling and processing, frequency higher resolution.
