  • Product Details
  • Company Profile

Brief Introduction 1. Nuclear magnetic resonance (NMR) is a new geophysical method to find water directly. 2. DSHS-3 NMR water detector brief introduction applies NUMI system to explore occurrence of aquifers from shallow to deep by changing amplitude



 

Applications

1. Seek underground water about 0~150m directly: the NMR abnormality
reflects the exist of underground water, the strength and range reflects water
outflow and area.

2. MRS method to distinguish whether there is free water in water-bearing
structure.

3. Locate the well combining with ρs abnormity feature in the water range.

4. Distinguish water quality: determine salt water or freshwater by resistivity
value.

5. Decide the pollution range and extent of hydrocarbon pollution water by
combining IP abnormality feature.

6. Evaluate dyke and underground water moving condition in geological
engineering, coast monitor, archaeology etc., detect old mineral and goaf.

7. Underground water estimation, seawater back flowing and underground water
dynamic monitoring



 



 

The technical parameter of DSHS-3 NMR water
detector has reached or exceeds that of NUMIS NMR water detector, which is made in France.
