TRS38G: Trisonde (Density)
The TRS38G probe provides long-spaced (LSD) and high-resolution (HRD) 4π global density measurements, based on the Compton scattering principle, as well as a natural gamma log.
This probe is intended for use in open and cased-hole conditions where a focussed sidewall density probe can not be deployed, or where calibrated results in g/cm3 are not necessary. It is widely used in the geotechnical sector where boreholes are drilled for reconnaissance, diagnostic or remedial works.
