Welcome To Gold Team
♥With the depth of resource exploration is from 50m to 1300m on the underground.
♥The tunnel advanced exploration distance is 300m.
♥ Underground polymetallic deposit, water search, underground electric property stratification,underground water-filled cave delineation and steep angle geological structure detection
♥ Coal seam and coal mined-out area (collapse area), water filled area.
♥ Geothermal resource, high-resistivity covered areas (such as carbonate rocks, igneous rocks and permafrost covered area), survey and exploration for oil and gas field.
♥ Water search and tracing of geological structure in tunnel
♥ As CUGTEM-4 intelligent upgrade, this performance become more powerful
♥ Selection of military IPC as operation platform with Windows PE, to operation intelligent and friendly.
♥ Using Light emitting diode as backlight LED screen, the feature with non- noise, highlighting and low power consumption to improve the date quality of field collection.
♥ Adopted dynamic floating amplification method to achieve the signal type collection, then enables our instrument operation simplified and convenience, so that reduce the data quality instability which caused by human factors.
♥ High-strength engineering plastic chassis triad as one of receiver, signal amplifiers, power supply system, with which reduces in size and weight, at the same time , easy to carry and construction .
♥ In humidity and dust environment, Water-proof, dust-proof and full-metal stainless steel of keyboard become more adaptable, it’s more sensitive to protect instrument better and live longer.
♥ Hot-keys makes field operation become so easy and simple
♥ The Original over-current protective functions: electric current pass through the receiver to select the matching automatically, and protection circuit.
