SGS
is pleased to offer down-hole video camera services with digital
video and audio recording capabilities. The camera has both down
and side viewing lenses with independent light sources. The probe
and attaching hardware are fully sealed stainless steel and can
be submerged in ground water and acid mine drainage. The camera
orientation can be determined to locate true positions of features
observed in the borehole. A custom centralizing assembly allows
for viewing in holes of any inclination. SGS also has a full
video editing capability to convert the video into CD or DVD
viewing formats.
