DEM series exploration engineering professional rectifier power supply
DEM series exploration engineering professional rectifier power supply
▲DEM series exploration engineering professional rectifier power supply
The DEM series exploration engineering professional rectification power supply is the characteristic of our company for the field operation of exploration engineering. It is specially designed to have a good seismic effect, high power density, small volume, high power supply control precision and good stability.
▲Applications:
Engineering geology (bridge, bridge foundation and bridge pier survey, roadbed, pavement and tunnel survey, reservoir, power station and underground engineering), environmental geology, hydrogeology, geotechnical engineering, resource exploration (oil, coal, metal ore, groundwater, etc.) Supporting power supply for industrial (survey) of liquid (gas) resources, geophysical and engineering quality testing, geological disaster management, etc.
▲Customer Testimonials:
