  1. Support various of synchronizations, by utilizing GPS synchronization, High-precious quartz clock synchronization, software synchronization, the measurement is quick and accurate, ensured repeatability and consistency of the instrument.
  2. High transmit power can satisfy various exploration tasks.
  3. Transmitter and receiver can be automatically walking, timing store emission current and receive primary field potential value separately to calculate precisely apparent resistivity parameters conveniently.


DJS-9 Direct Current IP Receiver

Features and Functions

  • The system transmitter has two synchronization mode (domestic initiation): delay synchronization after pulse and high-precision quartz clock synchronization, which allows high efficiency of field production, also convenient and flexible.
  • Time parameter recording: in –built high-precious clock, measurement results and measurement time are in stored together to easily calculate the apparent resistivit
  • Large Storage: can store 15000 group date, data protection against power-failure
