DSHZ-2 Proton Magnetic Detector

Brief introduction:

It is the new generation of proton magnetic detector with GPS function based on DSHZ-1 proton magnetic detector. The measuring accuracy is ±1nT, resolution up to 0.1nT, which is according to the demand of <Regulations of ground high precision magnetic survey> issued by original Geology and Minerals Department. It is portable, movable and base formed magnetic detector because its big storage capacity, high resolution and flexibility. It can do measurement of total field and horizontal &vertical gradients with 0.1nT resolution by changing probe structure.

Applications:

Earthquake warning signs monitoring, volcano observation and other environmental disaster geological works;

Engineering exploration like pipe detection etc.;
Detection of small ferromagnetic object and so on.

Geological map of magnetic survey in mineral prospecting: iron ore, zinc lead ore, copper ores etc;

Study ore's buried depth, vein direction, continuity, shape and size, ore scale estimation;
Oil &gas survey, and problems relative with oil &gas geological and earth structure; general survey;
Detailed survey, general survey and geological mapping;
Surface daily variation station of navigation and ocean magnetic measurement;
Fault location;
Archeology;
Hydrology;

Main advantages:
1. With RS-232C computer interface. Geomagnetic field and gradient measurement (horizontal or vertical gradient, special probe and bracket are needed)
2. Applicable in field survey or base station measurement.
3. GPS: can preset longitude and latitude of line end, then the meter will calculate each point’s position automatically; also display position information and error of set point location timely..
4. Built-in clock can be set by GPS time synchronization automatically.
5. Each point saves information of latitude, longitude, elevation and time. You can measure and store them timely.
6. Integration of clock: record time is stored together with the data measured at that time.
7. Large display, English interface, to display magnetic curves automatically, easy in operation.
8. Backlight LCD screen can be used at night.
9. User-friendly keyboard can be used by both hands.
10. It can be tuned full range automatically or manually. Can draw isograms and profile graphs with professional geological software.

11. Portable, it uses probe antenna frame and operation is easily fulfilled by one person.
