IPG800 Impulse Generator

800V energy supply for BIS-SH-DS S-Wave, BIS-SV S-Wave, and SBS42 P-Wave Sources.

BIS-SH-DS S-Wave Source

Generates horizontally polarized shear waves (SH) and compressional waves (P) in dry or water-filled boreholes (vertical or horizontal) up to 70m deep.

BIS-SV S-Wave Source

Generates vertically polarized shear waves (SV) in dry or water-filled boreholes for crosshole applications up to 100m deep.

SBS42 P-Wave Source

Generates compressional waves (P) in water-filled boreholes up to 70m deep.

SBS1000 P-Wave Source

For P-wave tomography between boreholes up to 1000m deep. Deployed using a logging winch with four-conductor cable.
