 DS-2  multi-frequency electromagnetic instrument

GEOSSUN Top quality most accurate gold detector wand

——Suitable for rapid investigation of mineral and water resources 

JSSP-2 time-frequency intensification-polarization instrument fusion time domain of the field of excitation and dual-frequency IP method as a whole, the main purpose is to provided dual-band or bipolar wave to the ground by transmitter, collects electrical reaction information for underground geological body through electrode measurement, automatically calculate the apparent resistivity, video frequency or viewing power rate after information processing, rolling play multiple measurement results on LCD screen scroll for the user to select and store. Users can achieve purpose of prospecting and solve geological problems through analysis and interpretation of these information.



Taking the two functions DC excitation method and dual frequency excitation method into account;

Carrying multi-function transmitter, heavy current (20A),high power (16KW);

Receiving system operating mode is flexible, not only can stand-alone fast scaning, but also be extended to isolated multi-channel simultaneous measurement;

Combined accurate GPS time synchronization and software self-synchronization ;

Automatic process self-potential compensation, gain adjustment, filtering etc, measurement results precision;

Accurately and rapidly measurement of ground resistance function to facilitate the field construction; 

Self-checking function, easy to detect equipment failure quickly;

Operation is all Chinese man-machine dialogue mode, easy to use; 



All temperature input correction and temperature coefficient of automatic compensation, suitable for a variety of temperature environment work;

Wide signal input, small signal measurement and anti-interference ability;

Complete digital signal processing technology, fast observation speed, high work efficiency;

Low-power design, continuous working time>12 hours;

Large data storage capacity, safe & reliable, function of data query and curve rendering;

Small size, light weight, easy to carry;
