VIP/ELREC high power IP instrument
At present, the high-voltage technology of French IRIS company has not been surpassed by any manufacturer. The high-power IP transmitter VIP5000/VIP 10000 specially designed for ore prospecting has a maximum output of 3000V and a maximum current of 20A, which is especially suitable for working in high-resistance areas. The simultaneous observation of ELRECPro 10 channels greatly improves the production efficiency. What's more commendable is that SwitchPro(24, 48, 72, 96) is equipped with an extended electrode conversion box, which brings great convenience for moving cables in the field. Only 900g portable handheld ELRECLite dual-channel receiver appeared, which greatly reduced the weight of field operation instruments and equipment.

Nuclear magnetic resonance water finder
Nuclear magnetic resonance (NMR) is the only geophysical method to find water directly in the world. In the mid-1990s, BRGM, the French Geological Survey, transferred the patented achievements of nuclear magnetic resonance water exploration technology, which had been studied by the Soviet Union for decades, to IRISInstruments. For more than ten years, the nuclear magnetic resonance water finder of French IRIS company has been verified by a large number of field data in more than 40 countries and regions around the world, and its ideal application effect makes it the only mature geophysical instrument with commercial nuclear magnetic resonance technology. Since the first generation of nuclear magnetic resonance water exploration system 1996 came into being, it has been greatly improved and perfected in detection depth, signal-to-noise ratio and suitability for field work. The latest generation of multi-channel nuclear magnetic resonance water finder NUMISPoly has a maximum detection depth of 150m, which greatly shortens the field data acquisition time and further improves the signal reading quality.
