  • Electrical Tomography Software

    Res2dinv - PASI srl

    This very popular software, developped by M.H.Loke, uses the method involving the Sasaki minimum squares inversion (1992) to produce a 2D sub-soil model starting from the data of apparent resistivity (up to 2000 electrodes). It is completely automatic and does not require that the user formulates a starting model. When using a state-of-art computer, the inversion of a single pseudosection will require only a few minutes.RES2DINV supports spreading types like Wenner, Schlumberger, Pole-Pole, Pole-Dipole, line Dipole, equatorial Dipole and other non-conventional spreading types.

  • Small size non-steady-state probe for thermal conductivity measurement

    TP08 - Hukseflux Thermal Sensors B.V.

    TP08 is a probe that offers the possibility to perform a practical and fast measurement of the thermal conductivity (or thermal resistivity) of the medium in which it is inserted at a high accuracy level. It works in compliance with the ASTM D 5334-00, D 5930-97 and IEEE 442-1981 standards. The TP08 is a small version of type TP02, made for situations where the length of the TP02 poses a problem. The standard TP08 probe has proven its suitability for soils, thermal backfill materials, sediments, foodstuff, powders, sludges, paints, glues and various other materials.

  • Marine Logging System

    SuperSting Marine - Advanced Geosciences, Inc.
