Profiler
The Profiler EMP – 400 is a frequency
domain, electromagnetic profiling system.
It can be configured to simultaneously
measure up to 3 frequencies between
1000 Hz and 16,000 Hz with a fixed
coil separation. By acquiring multiple
frequencies the user can select the
frequencies, which provide the best results
for a specific application.
Both in-phase and quadrature
measurements are recorded with a time
stamp. Output is the mutual coupling
ratio (Q) in parts/ million (ppm) or
apparent conductivity in mS/m.
All survey acquisition parameters and EM
data are stored on internal memory. Files
are structures in Excel spread sheet format
for simple download to a PC for immediate
presentation on commercial mapping
software packages.
For geology, ground water, archaeology
and environmental site assessment
