Receiver- T-VLF Radiowave

T-VLF Radiowave receiver

VLF System for groundwater environment and mining. The T-VLF is a radio wave receiver specially unsigned for high productivity surveys in groundwater, environmental and mineral exploration.

Features of T-VLF Radio wave receiver

  • VLF System for Groundwater Environment and Mining
  • Easy to use
  • Fast and automatic

Profiling System- PROMIS Multi-Frequency Multi-Spacing

PROMIS Multi-Frequency Multi-Spacing Profiling system

PROMIS is a slingram HLEM system using a transmitter loop to produce a primary magnetic field, linked by a cable to a receiver sensor located at a given spacing from the transmitter; the system measures the three in-phase and out-of-phase components of the secondary magnetic field induced in the ground by conductive structures. The profile is carried out by measuring a set of frequencies at each station, and by moving both the transmitter and the receiver to the next station.

Receiver- ELREC 2 Induced Polarisation (IP)

ELREC 2 Induced Polarisation (IP) Receivers

Elrec 2 is a two dipole Time Domain Induced Polarization receiver designed for deep resistivity sounding and high productivity surveys in mineral exploration. It has been designed for being both a user friendly and a very sensitive IP receiver. Elrec 2 measuring process has been optimized to provide the best possible accuracy in real field conditions.

Features ELREC 2 Induced Polarisation (IP) Receivers

  • Lightweight two-channel Resistivity and IP receiver

Resistivity Imaging- SYSCAL Pro & IP equipment

SYSCAL Pro Switch

The SYSCAL Pro Switch units use segments (seg) of multi-core cable which are reversible and interchangeable.

For instance, the SYSCAL Pro Switch 48 with 10m spacing has 4 segments of cable a, b, c, d, with 12 electrodes each, for a total line length of 480m. The SYSCAL is placed in the middle of the line, between segments b and c. If the profile to measure is longer than the line length, a ROLL ALONG technique can be applied where, after a first set of readings with (a, b, c, d), segment a is placed after segment d to form a new (b, c, d, a) combination etc.

SYSCAL R2

The SYSCAL R2 unit is a high-power system designed for DC electrical surveys applied to groundwater exploration, environmental studies, civil engineering, structural geology investigation and mineral exploration. Powerful: The SYSCAL R2 uses an external DC source for energizing the ground (800 V maximum output voltage):

  • 250 W DC/DC converter supplied by a 12V battery
  • 1200 W AC/DC converter supplied by a standard motor generator

Automatic: The SYSCAL R2 is controlled by a microprocessor for:

Resistivity Imaging- SYSCAL Junior Switch 48

SYSCAL Junior Switch 48

The SYSCAL JUNIOR Switch-48 is an all-in-one multi node resistivity imaging system. It features an internal switching board for 48 electrodes and an internal 200W power source. The output current is automatically adjusted (automatic ranging) to optimize the input voltage values and ensure the best measurement quality. The system is designed to automatically perform pre-defined sets of resistivity measurements with roll-along capability. Four multi-core cables with 12 electrodes takeout each are connected on the back of the resistivity meter.
